I sleep in a footed pajama, I like to be fully clothed to sleep, even in summer!
When I go to bed, I first need to smell the scent of my plushie (on his neck) before cuddling it! It's a thing from my very young age. This is something that remind me my toddler bed time and guess what, the odor being mine, it's the same one and it makes me feel very little.
Once I start to cuddle my plushie it takes a few minutes to fall asleep. My wife tells me that it's incredible, she needs to read a book at least 1/4 hour and when she looks at me after 1 or 2 pages, I'm already sleeping.
So yes, I need to have a skin contact with my nose, then just cuddling in my fully clothed arms is perfect.
