I've suffered Hypnagogia several times in my life where I have woken up and can see giant spiders running around my bedroom. I hurt myself once leaping from standing on my bed, over the spiders, to my door so I could switch the light on and attack them. Of course, when the light came on and I turned around the spiders were not there. My brain, not understanding where the "spiders" had gone convinced me that they had merely scurried under the furniture to hide, so I spent another couple of minutes trying to find them before I realized I had been punked by my own brain.
