Yes!
I love it, and it puts me in such a good mood for the whole day :)
Must be some kind of excess of 'happy' stimulation, wish it would happen more often!
Yes, I happened to me while I was at my parents' house. And it happened to my husband just the other night - hence this question. I think it is hilarious! And, like jonaj, wish it would happen more often.
No. I have never heard of that. My husband has never told me that I have done this. It would be funny to do this. What could be so funny to wake you up? Would love to know
Neither one of us can remember. Though there was a time I bumped into the wall while asleep and woke up then laughed my head off...but that doesn't count.
