My hallucinations. The worst was one that sat like a huge dog with matted fur just staring at me. It then began to move slowly and get up like it as coming for me before it just disappeared when I grounded myself. Another spook was a sleep paralysis episode where I wasn't sleeping right and was disturbed in a deep stage of sleep. I couldn't open my eyes, I couldn't control my breathing, i couldnt speak, and I couldn't move my body. The only thing that came from my mouth was breathing and whispering of my attempts to shout. But it got worse since while I was in this state I felt something push down at the bottom of my bed where my feet were, i even felt my feet fall that direction of the pressure, and I got an immediate cold rush. I couldn't open my eyes to see what was there. The pressure then moved upwards on the right side of my bed, getting up to me elbow before it disappeared and I came to. It took about an hour before I could fall back asleep.
