Hello all! :)

I really love amnesia fics, and I am looking for some recs on good amnesia stories. Particularly looking for three types of fics:

1. The memory loss leads to some sort of misunderstanding or general confusion.

2. The amnesia leads to two people realizing their feelings for each other or getting together (Castiel loses his memory, and wakes up thinking he is already in a relationship with Dean or something like that.)

3. One or multiple people lose their memory and it is a challenge to figure out who they really are.

I am interested in anything that fits into one of these categories, in Supernatural or in RPF, any pairing or gen. I just really love this sort of story and would really appreciate anything I can get along these lines.
