Two feelings for which there must be a German word that describes each perfectly.

The habit of completely forgetting that you used to live in a basement appartment rife with wood bugs once you have moved into a new appartment.

The feeling of seeing an advertisement on a bus shelter for a rave that you used to attend back in the day when it was word of mouth with no security, no searches, and now you find that it is an all-day event hosted by Ron Jeremy and the Coors Light Girls.
