Am I delusional or is there a logical explanation for this

  1. Jan 12, 2007 #1
    I've always wondered since I was a kid, I would lay down and have a blanket over my eyes sometimes while looking through it during daylight or at a light. If I focused just right, I would slowly see squiggly lines and things just slowly floating by like a transparent layer over what I normally see. I always figured this was normal and used to equate it to looking through a microscope. In fact, I used to believe it was me seeing microscopically when I was younger. I don't believe it anymore nor do I think I'm hallucinating. Is there any optical specialists here?

    That's normal, everyone sees those at some time. Here is an explanation with a picture.
