Did it once at about 3am with headphones on. Not really up for it again.. I sit close to a large mirror fixed to the wall in this room and whenever I get jumpy or startled I prefer to avoid looking at big mirrors (old childhood scare) and it takes me a while to calm down so I can turn off the lights and go to bed (and therfore walk by the mirror in the dark).
I am curious as to what else happens in the comic though.
