I have had a half-awake encounter of some sort a few years ago. I'm not sure if I really saw this or not to this day.
I woke up in the middle of the night a few years back, half-awake with my eyes squinted and my face turned facing the left flat on my pillow. I saw a decaying, dead human figure...similar to a zombie I guess...laying down next to my bed. Not laying down like a normal person, but in a creepy, slowly-lowering way (as if it was on a hospital bed being lowered slowly) onto the floor. I sat straight up in bed and looked down onto the floor and saw nothing.
I have never had any other encounter before or after this, but as I have said...I'm not even sure if this was real or just my subconscious messing with me. It was probably the latter. Nevertheless...very freaky.
