Well-not the ones that take 45 minutes-been there done that.
But there is something comforting about being all enclosed with soft music playing in your ears. My wife likes to say I enjoy cocooning. I do like to wrap myself in a blanket over and over and looking like a mummy just lay there. I go to bed like that and never move. I wake up in the morning in the same cocoon. She-OTOH-is all over the place, kicking the blankets off and then putting them back on, moving her legs like she running a sprint, etc.
I fake injuries so I can get into an MRI machine.
