Kesha

According to Kesha, she's encountered one particularly "sensual" spirit.

Asked about the experience by E! News, the 36-year-old singer said: "I had something wake me up while I was in bed with my boyfriend at the time, and it was a touch down my body.

"I woke up and looked at the end of the bed, and there was an apparition of a woman. So, full disclosure, I never slept with a ghost, but she did wake me up in a very sensual way."
