Misplaced Sanity

Where has my mind run off to these past few days?  I feel fine, but crazy events have been happening all around me.  Who causes these events?  No one; it's just me.  Oh yes, somehow I have done the following since Friday:  

• Within an hour, ended up with 3 different glasses of water to drink in my kitchen...all at different levels and in different places because for some reason I didn't realize I'd already filled one.
• Frantically searched for my keys in my purse at work today, and they were no where to be found.  I discovered them in the refrigerator, inside my lunch bag with my leftovers.
• I e-mailed myself from my work e-mail to personal...but not on purpose.  It was supposed to go to a friend, and I just couldn't figure out why she hadn't responded.
• When I was thirsty at work, I grabbed my vase of water on my desk and took it to the kitchen instead of my glass of water to refill.
• And lastly, I held my glass of water up to my mouth to drink during our department meeting in the conference room, and somehow missed my mouth and poured the water directly onto my chin and down to my chest while my boss was talking across the table looking at me.

Is this temporary insanity due to lack of sleep?  Or perhaps something else?
