I occasionally have dreams about my highschool GF from 10 years ago, even though I rarely actively think about her. It's not the first time I've dreamed about her though, apparently it's more of me unconsciously missing the feeling of being in a relationship and using an old ex as the embodiment of said nostalgia.
Yesterday was the longest uninterrupted dream about her I've ever had about her though. Waking up felt like a lie.

Azur Lane. (She looked a bit like ingraham back then)
