Ok, I like to wear a bandana over my eyes because it helps me sleep AND it is a good non-movement RC. So last night, I put one on and fell asleep almost immediately, but then I had it on in my dream too! I would stumble and fall, and even uncovered my eyes for a while. Because I never was able to see with it, I never thought it was a dream, so why do you think it did that?
It’s hard to say. I don’t wear one at all and I still have sight issues in WILD’s and low lucids. It could be a memory thing, expecting it to be there, or it could be that you feel the blindfold so your mind assumes you can’t see. If it’s a common occurrence then maybe it’s worth experimenting without one once or twice. Otherwise, I will usually yell (keyword:yell) for my sight back, and that usually helps, if only temporarily.
