The first times I tried WILDing, I panicked when I encountered new feelings (heavy body, etc) as well as sounds hallucinations one time, mostly because of the novelty of the experiences. I guess it's normal because those things are new, and you don't feel too much in control or don't know what to expect.

Just keep trying and practicing, and you'll get more and more at ease with the different feelings and situations!

Bonne nuit et fais de beaux rêves!
