It sometime occurs to me when i go into a room purposely going to pick something and when you get there you have no idea why you are there. It mostly happens when people are stressed or under a lot of pressure in doing something.
Yes. Then you suddenly remember why, walk back into the room, and forget - again. Gets worse as you get older. (Often because you're anxious to do several things at once & the order gets all mixed up.)
Million times a day,saw something on the news other day,One reason they believe this could be happening as we walk thru a door way our brain thoughts leave that room as we walk out.That is why most time we walk back in and remember what we forgot.:)
