Sleep Paralysis?

Ever since my episode with this entity last Tuesday, I've been very cautious when sleeping in my own room. The first few nights, I slept at a girlfriend's house. She went on vacation for the weekend so I was forced to stay home.

I hung a cross over my bed and kept my bedroom door wide open so that the light from the hallway would shine through. I woke up in the middle of the night and saw a faint, smaller version of the dark black shadow in the corner of my room. I moved around a bit and went back to sleep. I felt strongly at ease when I awoke in the morning; like the cross was working and that I would have no more problems... However the thought of this being in my room still completely freaked me out.

So then I tried sleeping with the lights all on Sunday night and had no problems at all... I must admit though, it's difficult to get a good night's rest with lights in my face. Monday night, I decided to put my three year old son in bed with me and turned the lights off, kept my door open again so that the light of the hall would shine through. Again, no problems at all. I figured this was the best way to assure that they would no longer bother me while I slept.

Last night, exactly one week from the past episode, my son was hardly tired and kept running from my bedroom, across the hall to my mother's. Our bedroom doors are diagonal from each other, and I can clearly see her when I am lying on my bed. I was ready for bed and my son obviously was not. My lights were all off and the fan, at the foot of my bed, was on low speed (it tends to act crazy when I put it on medium or high speed). The lights from my mother's room and the hallway shone into my dark bedroom, giving me a sense of security besides the light from my laptop.

My son then started running around so my mother closed her bedroom door. My room became noticeably darker and my laptop shut off on it's own. All of a sudden, within seconds, my fan started shaking and the speed started to fluctuate without my touch. I felt a dark cloud over me and I started to convulse. I was completely conscious, yet I could not scream, I could not move; I could not even close my eyes. I felt my heart racing and wanted so bad to scream, and then, what seemed like decades later, I was finally able to stop shaking and jump off my bed. I quickly turned my light on and sat on the edge of my bed until I caught my breath.

Needless to say, I didn't go back to sleep in my bedroom last night.

This all seems to me what could be defined as sleep paralysis, however I had never even gotten the chance to shut my eyes, let alone sleep for a minute.
