Meditation crumples my senses!

[Baotrader]

I don't know the right verb: crumple or cripple or some other verb to correctly describe it @Leo Gura can you help me? 

Yesterday I sat in meditation for 12 hours and I lost my senses. I could not tell it was day or night and the strangest thing was there were times I had to take a few seconds to distinguish myself from a wall in front of me. I became the wall@!! And I was damn awake. So scary experience
