Ugh, I had this happen once! In my dream one of my friends got on all fours and started making this very annoying noise, we were all pissed about it and it was extremely irritating. I woke to realize it was my alarm, lol.

What I did was get an alarm clock with two settings. I set one to go off at a certain time, then another to go off 15 minutes later. I've never slept through both.. and I would hate to see two people on all fours making those kinda noises!! What a dream THAT would be huh? Hahhaa.... good luck!
