Odd Question, Bearded Dragon

I have a bearded dragon (Frack) who is very fond of falling asleep on me as it starts to get dark, and I was wondering if anyone else has had their beardies do this... also, does anyone know if the extra heat from sleeping on someone could cause them discomfort or annoyance? Or do you think it might be safe to just let him sleep the night away?

As I said... really odd question, but he's been grumpy recently (shedding) and seems happiest when he's asleep or falling asleep on me XD

If you roll onto him you will squish him. Your body temp is lower than their basking temp so the heat is not an issue.
