A bit of all of these to be honest (not number 13 though because number 13 looks like it’s not a thing) Though recently I’m big into number 5, love cuddling my pillow
but then it may change to number 18 if the tv is snoring.
I’ve been told I sometimes sleep like number 6 but with my hands and arms fully enveloping my head, not under the pillow like in the pic.
