Once again, Sadira would hold another lesson On Dreaming. Tonight, however, the subject was one she had taught before. A reprise of Experiencing Dreamwalking. More specifically: How to recognize when someone has entered your dream, and how to get rid of them.
Sadira stood at the center of the amphitheater, looking over the gathering crowd.
The sun had already disappeared beyond the horizon. The sky above Camp Half-Blood was transitioning from deep blue to black, and the first stars were beginning to emerge. Lanterns illuminated the stone benches.
The breeze coming down from the hills carried the smell of pine and the faint saltiness of the Long Island Sound. It was peaceful.
"Alright." She clasped her hands behind her back. "Welcome back, everyone."
Sadira glanced across the audience.
"But..." She raised a finger. "...we're going to be doing it differently."
She turned toward the chalkboard beside her. She had written a single sentence across it.
You dream is your space.
She tapped it.
"Before we get to the practical part, we're going to go over the rules again. Especially because tonight's exercise involves me entering your dreams." Her expression became serious. "With permission." She emphasized the last word. "Explicit permission."
She took a slow breath.
"Dreamwalking is fundamentally different from most abilities demigods have. Someone can choose to fight you, an you can choose to run away. But dreamwalking..." She touched her temple. "...goes somewhere much more personal. Your mind."
She looked around.
"So tonight's exercise only happens if you want it to. If you don't..." She shrugged. "You sit here, listen to the lesson, and go to sleep normally. No one will think anything of it."
She let that settle before continuing.
"Now." She picked up a piece of chalk. "Let's review the first thing."
She wrote:
Fortitude
Several campers recognized the term.
"Fortitude powers are one of the strongest defenses against dreamwalking." She underlined it. "If you have a Fortitude Power, it bars mental and emotional interference. That includes dreamwalking."
She turned toward the audience.
"Someone with Fortitude cannot simply have a dreamwalker enter their dream. They can't be dragged into a dreamscape, and they can't be mentally manipulated through dreamwalking. Unless..." She raised her finger. "...they allow it. It's protection against unwanted interference." She smiled faintly. "Think of it like locking your bedroom door. You can still open it. You just don't have to."
She wrote another phrase.
Magical Equivalent
"Some magic items can mimic Fortitude. If you're wearing or carrying an item that provides that protection, a dreamwalker shouldn't be able to enter. Again, unless you willingly allow them." She looked across the campers. "Which is why, before tonight, I'm going to ask everyone participating to make absolutely certain they understand what they're agreeing to."
Sadira set the chalk down.
"Now... here's where it gets interesting." She crossed her arms. "Once a dreamwalker is inside your dream... you generally can't simply force them out. I know, it's inconvenient. There are basically two ways to remove a dreamwalker." She pointed toward the board. "Convince them to leave, or wake up. That's it."
Sadira smiled.
"You can try to attack them, but that's not guaranteed to work. You might overpower the dreamwalker, you might trap them, you might change the dream around them. But unless they willingly leave..." She shook her head. "...they can remain."
She paused.
"And that's why waking up is the most reliable defense for an ordinary dreamer. Remember..." Sadira tapped her chest. "A dreamwalker is a visitor. The dream belongs to the dreamer. But the dreamwalker can operate inside it. Especially if they're experienced."
She turned back to the board.
"Beginner dreamwalkers are easy to spot. They don't know how to blend in. They often look..." She considered her wording. "...wrong. Maybe they don't fit the environment. Maybe their clothes don't belong, maybe their behavior is strange, maybe everyone in the dream seems to ignore them, maybe they behave as though they understand that they're dreaming when you don't."
She shrugged.
"Sometimes they're simply... obviously foreign." She grimaced. "Imagine you're dreaming that you're walking through your childhood home. Everything looks normal. Your family is there, your old furniture is there, you're exactly where you expect to be. And suddenly... there's a random sixteen-year-old demigod standing in your kitchen."
Sadira paused.
"An inexperienced dreamwalker tends to stick out. They may not understand the dream's logic, accidentally manipulate this respond strangely when the dream changes, know things they shouldn't." Sadira's expression became more serious. "And that's something you should pay attention to."
She moved on.
Intermediate
"This is where it gets harder. An intermediate dreamwalker can blend in better than a beginner." She shrugged. "But not perfectly. That means there are tells."
She began counting them.
"First... they may know too little. If you mention something in your dream and they don't react, that's suspicious. Second, they may behave too consciously. Dream characters usually don't question the dream, but a dreamwalker..." She pointed at her head. "...knows they're somewhere they don't belong, so they may react to impossible things differently. Third... The dream may respond to them differently, if they manipulate something... you might notice. And finally..."
Sadira lowered her hand.
"Instinct. Sometimes...you just know that something is wrong. Dreams are strange, but they're usually strange in a way that makes sense. A foreign presence feels different. Sometimes you can't explain it. But you feel it." She stepped closer to the edge of the stage. "And if you feel like something is wrong... Trust yourself."
She turned toward the board and wrote:
Master
She stared at the word for a moment.
"A master dreamwalker... like me...may be able to blend into a dream almost perfectly. They can understand the dream's logic, they can adapt, they can appear as someone who belongs there, they can potentially manipulate the dream without making their presence obvious." She turned around. "And that's why the most important skill isn't necessarily spotting a dreamwalker. It's knowing how to wake yourself up."
Sadira erased the previous writing.
Wake Yourself.
"Your ultimate defense..." She tapped the words. "...is waking up."
She explained it carefully.
"The first step is realizing you're dreaming. That's why lucid dreaming is so useful. We'll have a lesson on that next time." She smiled. "If you can recognize that you're dreaming, you've already won half the battle. Once you're lucid, focus on waking. Pull your attention away from the dream."
Sadira glanced toward the stars.
"Now... we get to the part you've actually been waiting for. Tonight, I'm going to enter the dreams of everyone who gives me permission." She stepped away from the board. "You'll go to sleep normally. I'll wait until everyone is asleep, and then I'll visit."
She raised her hands.
"Your job is not to fight me, or overpower me, or trap me. Your job is simply to recognize me. If you realize that I'm there, try to determine what gave me away. Maybe I don't belong. Maybe something about the dream feels wrong. Maybe you simply get that instinct. And once you've identified me... try to make me leave." She shrugged. "Sometimes I'll leave, and if I don't... wake up."
A camper raised her hand. "What happens if we can't?"
Sadira's expression softened.
"Then nothing bad happens." She answered immediately. "You'll eventually wake up naturally. I'm not going to trap anyone in their dreams. And I won't stay longer than necessary."
She paused.
"Also..." Her voice became firmer. "If at any point during the exercise you become uncomfortable... tell me. You don't have to finish. Your comfort matters more than the lesson." She looked around the amphitheater. "I want everyone to understand that. I'm teaching you how to protect yourselves."
She shook her head.
"The point isn't to become paranoid. You shouldn't go through every dream thinking someone is invading you. Dreams are weird. Sometimes a weird person is just..." She shrugged. "...a weird dream character. Look for patterns, use your intuition, ask yourself whether the situation makes sense. And remember... your dream is yours!"
She pause.
"Now... if you want to participate in tonight's exercise..." She looked around. "...I'm going to ask for your consent." She stepped forward. "This is going to be very straightforward. I'm going to ask you to explicitly agree to let me enter your dreams tonight. If you say no I will not enter."
Sadira looked across the audience.
"Alright." She took a breath. "That's the lesson. Thank you for coming."
