What happened Last Night?

I woke up choking last night and was unable to breath. I stood up on the bed, and started attacking the faux mahogany wood blinds. I managed to tear off the valance, and break two slats.

I don't know why. I though of Sleep Apnea, but no one in my family or extended family has it. Also, I don't fit the "ideal" candidate for it.

I am on several medications, so if nothing else, I'll blame it on them.

If anyone knows of a Wake-Up-Choking-Attack-The-Blinds Syndrome, please let me know.
