Is this weird?

My boyfriend has an issue with nightmares. He has a lot of trauma from when he was a child. I told him if he has a nightmare and can't go back to sleep to wake me up and we can talk about it. He will usually stay up after a nightmare and be tired in the morning, but when we talk about it he can go back to sleep. My brother says that's weird and that a grown man shouldn't need to talk about bad dreams. Is it really that weird? I never thought anything of it.
