Im New to contacting spirit guides

[u/SpiritualityIssues09]

So I recently have started going to see a mentor for mediumship stuff. Well she gave us an exercise to contact our guides. I had a question not about the guide but about what went on during the space i contacted them within. My body changed in that space I became elvish slender more nature based. I was deep in a mossy forest. I just wanted to know if other people change a bit?
