Exclamations upon Awakening

When I get out of bed for the day I’ve noticed that I’ve developed this odd habit (as if I didn’t have enough of those already). When I actually sit up (this could be after lying awake for some time working up to it) I blurt out the first thing that comes to me, off the top of my head. Sometimes it’s just something I thought of while sleeping that I think is funny “monkey biscuits!”. Sometimes it’s something important I’ve been thinking about while sleeping “Go to the bike shop!“, “buy bread!”, “water the oregano!” it’s really quite helpful when I come up with something I needed to be reminded of. Then there are mornings like today. I sat up and loudly exclaimed “Sidney Poitier!”, and I don’t have any idea why. Should I go rent “Guess Who’s Coming to Dinner”? Is someone coming to dinner? What does it all mean??
