Befuddled

When I go to bed at night as tired as i am my brain decides to switch on and keep me awake.I think of all these things I need to get off my chest and blog about.I remember stuff I need to do cos I forgot to do it during the day
Eventually I'll fall asleep for 2or 3 hours,then when I get up I can't remember anything that I wanted to write about or any of those things that I need to do!
I have it in my head today that there is something really important I need to do,but I have no idea what it is,the time 2.30 seems to be prominent but I'm not sure if I'm meant to be somewhere or someone is coming over.
I know I need to make a phone call but to who and what about,has me completely confused.
I've tried writing stuff down and making lists but then I misplace my list,I think this is what loss of cognitive function is.
It's only 5 past 8 but I think I might go back to bed and write this day up as a loss.
