I have a litany of different parasomniae. Sleep walking and talking. The occasional paralysis, regular night terrors, the very odd waking hallucination. And rarely remember my dreams. Here's my experience:
Sleep talking: Never remember anything about the dream. I do respond incoherently apparently.
Sleep walking: Can remember the edges of the dream if woken up. Dream logic still holds for a good 10 seconds or so from waking up. I tend to hand my husband wads of clothes. He's figured out if he just orders me back to sleep I'll do it.
Night terrors: Never remember anything, and to my understanding occurs during nrem, so you shouldn't be dreaming anyway. I startle my spouse often. My grandmother also had them all her life.
Hypnopompic (read: after waking up. Contrast hypnogogic) hallucination: Been a long time on this one. Kinda like a movie. You see and hear something then all the sudden it vanishes. Only ever happened a couple times ever.
Sleep paralysis: Terrifying. Keenly aware that I'm fully conscious and cannot compel anything to move. Not even my eyelids. Lasts for what feels like forever but is probably a few minutes. Worst one for me by far. Thankfully rare. Edit: It is my understanding that people hallucinate sometimes at the same time. Hence the origin of the sleep paralysis demon.
