I didn't sleep for six days after my daughter was born....due to pain drugs and the fact that she was losing weight and had to be fed every hour around the clock.

Yeah, I kept thinking I saw the cat everywhere I went in the house. I would turn to make sure it was her, and I would realize she wasn't there. It was more like if I saw anything in my peripheral vision, I would assume it was Bootsie, more than actually seeing her. I thought I could hear her purr.

Once I slept it went away.
