I would never sleep elsewhere the first night of a move. Years ago I was woken in the middle of the night by someone trying to break in. Presumably someone who knew there was a house move afoot and looked through a window - curtains not yet hung - and saw piles of boxes. I was alone in the house and the phone was downstairs before the days of mobiles.
I put the light on and crept downstairs to ring the police and when they came a short while later they told me off for putting the light on as it scared him away. Nowadays I imagine that they wouldn't even come out at 4 in the morning!
Forgetting where you left your keys does not mean you are “losing it”
