I've been doing this too - only recently mind! normally after a propper session on Jamesons or Jack Daniels? For the last year i've had a pretty stressfull job, but that doesn't bother me untill obviously i sleep!

I was on a night out in Bournemouth for a mates birthday and got completly wasted, when i got back to the hotel i crashed out for 10 mins then apparently jumped up ran to the window and started peeking through the curtains commando style - going on about snipers in the trees! The bird i was with told me to get back in bed and stop being a twat, so i apparently did... untill 10 mins later i shouted out "oh my god the rooms on fire!" jumped up again, packed my bag with god knows what, told her she could stay if she wanted but i was outta there! she woke me up just before i got to reception absolutely pissing herself. i have never lived that down with her or my mates!

Decided to see if staying off the whiskey and Bourbon solves the problem!
