Dissociative amnesia (also called psychogenic amnesia) is a thing. It's something I used to experience a lot. I don't know how prevalent it is in BPD, but I do know that it's a very real thing that some people with BPD experience.
OP, dissociation and derealization are what got me diagnosed BPD 10 years ago (along with general Cluster B-ness). I had been diagnosed PTSD around the same time (from recurring childhood trauma/abuse). From what I understand dissociation or derealization are common in BPD, which isn't surprising as many people with BPD have in common serious child abuse and trauma. I used to check out completely and would lose hours--entire shifts of work or something. I've long since identified triggers and have worked through most of them or learned how to avoid them. I also used to experience the dream-like sensation of things not being real. When I was younger I would also zone out even when people were talking to me. It really doesn't bother me much anymore, and it's been years since I had dissociative symptoms.
There's a PTSD video I really like that I think demonstrates dissociation (and other trauma symptoms) really well. I'll link it if anyone is interested, but huge trigger warnings.
