Snoring with a full belly (i was so deep in sleep)

I ate more than usual that day and when I lay down on the couch, I was instantly knocked out and fell into such a deep sleep that I didn't notice anything anymore. My friend said that around minute 5 he briefly tried to push me away so he could sit on the couch too, but I didn't feel anything. And he said I drooled so much more than usual, oops. I should probably eat more often for a good night's sleep. Anyway, in the end he woke me up and we watched a movie together... well, he did at least; I fell asleep again on his shoulder after 15 minutes. ^^"
