This happens occasionally. I also used to see huge spiders bigger than my hand coming down at me in the dark. It's weird because my eyes are open and I'm staring right at it and watch it run right across the ceiling and then it disappears behind the curtain above the head of my bed. Of course it's not there afterwards.
When it happened I had my light on and was dosing off on my back snoring and happened to awaken and see it right on the ceiling. I'm pretty sure it's something to do with the space between dreaming and being awake, but if I didn't know any better I really would of thought that I saw a rat!
What I wonder about is how when I'm sleeping my mind can know where the ceiling is and then the moment I awaken place a very real image of a rat on the ceiling running across it and then hiding up behind the curtain. Also why am I always seeing spiders usually? Why is it always and insect or a rat? Actually tonight was the first time I saw a rat, it's usually spiders like I said. I'm afraid of spiders and I guess I would be of a rat too, maybe that's why.
Anyways, either it's an illusion or it's something real running across my ceiling. The funny thing is is that before I opened my eyes I could've sworn that I told myself (within a split second) that "watch there's gonna be something running across the ceiling like there usually is" and of course there was! I followed it as it ran very quickly and hid behind the curtain on the ceiling.
What's strange to me is that my eyes are following something on the ceiling, but most likely nothing's there. So this image is taking place inside my mind and my mind is convincing me that a rat is on my ceiling. Life is strange. Also, these things never really frighten me and I'm glad! As much as I saw the rat running, at the time deep down I knew it wasn't real and that it would disappear. The spiders do scare me kind of though. I usually end up awakening and then jumping quickly out of the way (it's usually falling from the ceiling) and then quickly turn the light on. Of course nothings ever there when I turn on the light. Darn, I'm afraid of beautiful women, how come they never appear instead when I wake up?
