Sometimes she packs her bags and puts on the bed... When I ask her where she is going? She says aren't we going somewhere, or I thought I was going somewhere. Other times when she puts her bags on the bed, I ask her why she did that and her response is I like it there. She also seems to be accumulating obsolete items like finished cereal bags, washes them, folds them up to keep. I asked her what she was doing and she said she wanted it because she likes it. I told her that if she needed a bag here is a freezer ziploc bag instead, but use it, don't just take it and look at it or put it away somewhere. Oh and also she is constantly rearranging items and every time she does that she can't remember where she put things and why she moved them to begin with...This is my first time caring for an older adult...is this a normal part of dementia? And is there anything I can do to stop the behavior?
