I haven't had a dream where I had a mind collar...But I did have a lucid dream where I was in my basement just sitting on a chair. Then I thought "Wait...Hey, cool! I'm dreaming! Ooo...Maybe I can fly? I'm gonna try!" Then when I got up to try it my mom called..And I'm like "Wait I have to try something!!" she kept calling me. Everytime she called I would get pulled closer and closer to the stairs. I was eventually screaming "NO MOM IM DREAMING STOP!" And I knew it was a dream and that I didn't need to listen to her, but I wasn't in control.
