Anyone else get hypnogogic/hypnopompic hallucinations? They're really scarey til you understand what they are, then they are really amazing! Associated with sleep paralysis they are the basis of a lot of claims of night-visits by witches and aliens. You really believe there is someone in your room, and you can really feel them touching you, holding you down, sitting on your chest etc. All the more terrifying because you are awake and concious at the time - its like your subconcious rises up & dreams, your concious mind is still wide awake, but you can't move or call out because whatever it is that inhibits movement when dreaming (so that we don't generally act out our dreams physically) has kicked in.
