I have a friend who says she woke up one night and could not move at all. No matter how hard she tried she couldn't move. So i knew she was expeirencing sleep paralysis, but she said she had takin nyquil before she went to sleep and she said she had experienced it before without the nyquil. I just thought it was a huge coincidence that the same night she took nyquil she just happened to have the second SP incident in her life (the other time was when she was sick and she was not sick when she took the nyquil). Has anyone else heard of nyquil maybe causing SP? And she does not take nyquil frequently.
