Yes its normal...I do it too even than I dont feel as safe but definitely better when my feet are tucked..id b crazy to go to sleep with my feet untucked.when I have I have had really bad nightmare...

Lol..totally not normal...hey its nothing bad though...while my feeties dont reek bad bad I wouldn't enjoy and like sneefing them ...or anyones else for that matter.except maybe babies feet...babie...

I dont think its normal but certainly not wrong and I wouldn't have anything against it..your not harming anyone and your having fun and making yourself happy..so you shouldn't worry greatly about it.
