He Was Killed by a Nightmare

Synopsis:

Rekindled romance + top + amnesia + accident.

Content warning: It isn't a mystery. The author just isn't clever enough to make it one.

The dreams grow increasingly real, and the faces of the people in them become clearer. Sealed memories return, but the people who left may never come back...

The serious version:

After losing his job, Liang Zhou often falls into bizarre, fantastical dreams. In one of them, he meets someone who should have been dead.
