I'm very,chronically sleep deprived and I see giant (about the size of a large dog) insects quite a lot, it doesn't bother me as I'm not afraid of insects, I also see small insects but they vanish when I try to look at them closer ( as opposed to real insects which don't). I have also had sleep paralysis a few times and it is pretty scary esp as it tended to happen when I was already feeling vulnerable, it felt a though a person was lying on top of me, I couldn't move at all and when I went to scream it was although they had their fist in my mouth so no sound came out.
