Have any of you ever had the dream where you're standing in front of your class and suddenly - horror of horrors - you realise you're naked? A classic anxiety dream, I understand. Well, it happened to me in Second Life on Monday. I lent one of my (female) students my avatar to use while she was waiting for her confirmation email with her own user name and password. Next time I strolled past her computer I noticed I (my avatar) was dancing in a bar. Topless! At least, wearing a bra top but not wearing the modest, decent jumper I made for myself. The student explained she had taken off my (avatar's) top because I had said I was hot. And indeed, I had been moaning about the heat in the real life labs.
Apparently there is a bug in SL which sometimes means you find yourself entirely naked for no reason. It happened to a colleague at another uni in front of his class. So if you're prone to anxiety dreams, don't use Second Life. :-)
