My partner has full blown conversations in sleep

This is sleep talking on another level. Sometimes I can figure out who he’s talking to based on the conversation. I think it’s due to some unresolved trauma. I don’t wake him up because I read if you wake someone mid night terror, they’ll likely recall the dream whereas you let them sleep through it, they’re likely to forget it.

He doesn’t seem to remember much in the morning so I just pretend I didn’t overhear his dream conversations.
