What Could Be The Reason For Sudden Feeling Of Being Disoriented ?

I had a.... really weird experience last night. I think I might have reacted to my medicine or something. Either that or I fainted while trying to sleep [I have fainted before and it disoriented me to the point that I didn t feel right for days]. I was disoriented and everything in the room was warping and moving or forming shapes. I reached out to touch the corner of the table because it looked like it was forming a mouth and I recall thinking this is wood but I couldn t feel anything. In fact, my arm seemed longer than usual. I was masturbating, though I didn t make a conscious decision to do so. And during, I kept thinking if I just get there it will stop. But that was the only thought going through my head. It was a lot like a dream but it wasn t one, I can assure. After some time, I regained mobility and got up and went to the living room to tell my family that something was wrong. My eyes couldn t focus and I was so light-footed that I kept falling over. What s wrong?
