Early Dementia?

The garage door person was coming over to give us an estimate, so I went to get my car keys to move my car across the street before he came over.  It took me walking a couple of rooms to get the car keys.  Then I got the keys, went outside, and saw my car parked across the street.  I had moved my car already!  Must have been just a half hour earlier, and I didn't remember doing so at all...  scary...  (we do have a ton going on right now with work + the move to Denton, I'm telling myself...)
