I've been having such vivid dreams for the past few months, possibly as a side effect of sertraline?

Last night's dream was pretty dark. I was having memories of a child I'd had, things like her first day at school. I could remember her but couldn't find her. Then I remembered that she'd died shortly after birth, and that I had her dead body in a box in my wardrobe. I told my husband and we got the box out and opened it. She moved her eyes and legs, but my husband was telling me she was dead and that we should arrange a proper funeral for her otherwise it would be like she never existed. Her name was Alison.

Just wanted to write that down. I don't dream journal, but maybe I should.
