Dream or Memory?

I was in a room with two men, both in dark blue dress uniforms for some military. I think they were my brothers. It was an older time period. The one where they had those old bayenette rifles and swords more than, say, handguns. I was a female. So we were in this room, and I kept hearing and seeing strange things and telling my brothers. Once I saw a man's face in a darkened window, and I ran and told them. I began carrying around one of my brothers' swords with me because I was frightened. I heard noises from the other side of the door, and I heard a toilet flush (not even sure if that was a thing back then). I remember standing in an alcove, behind a curtain, looking out a window with one of my brother's on either side of me while I clutched the sword and stood with them, terrified. These events took place over the course of a night slowly turning into day, and I was terrified because I somehow knew I would be the last one standing and could not understand why this man was toying with us. I woke up before the man ever came in that room though.

Also had some dream about going to prison, but I don't really recall all tbe details of that, if any.
