What dream makes you feel sad about not remembering the details?

My mom passed away about a decade ago. I have no real solid memories of her (depression, ADHD, memory difficulty in general, etc.) beyond photos and no videos, and I have aphantasia so I can’t really picture her while awake, but sometimes I see her vividly in my dreams.

So I kind of always feel sad that I don’t remember my dreams with her since I don’t really have much to remember her by, but it’s bittersweet because I do like when she shows up in them.
