Not really important, but super cute...

Hahahahahaha, he does not snore, although it would be quite cute.

You can tell they're sleeping if they are huddled in a certain spot for a while, or when I am holding them, he'll just sorta "power down" and sit in one position for a while until I move my hand or something brushes up against him!

This is along the same topic, and I thought this was pretty cool... Scientists have found out that jumping spiders are capable of REM sleep and are able to dream!

Here is an article about it....

Wow, that's AMAZING! REM sleep! Who even thought to look for that? Thanks so much for sharing that-

As far as knowing when they're asleep- it's sorta like snakes*. (*Except for the ones with round pupils- when they're asleep you can tell because their pupils sink to the 6 o'clock position, instead of centered. Of course, when you look, it tends to wake them up- so you have to look fast, quietly & preferably without a flashlight.)
