dreams...?

I titled this the way I did b/c I didn't know what else to title it..lol
anyhow this happened a few weeks ago. I had this dream I felt like I was
suspended in air, watching myself as I walked down the road of an old house
that belonged to my father in law, and then myself for a time. As I approached
the house, I saw a younger girl about in her late teens or 20's on the front porch/steps of the house. She had longer
dark hair and was wearing dark clothes: kind of gothic-looking. But, I wasn't
scared, though. Upon meeting her, we
proceeded to go inside, and I remember having a feeling that we were trespassing and really shouldn't be there. To my surprise, it looked different from what I
had remembered; to a degree. The basement was fully carpeted, which later on
I asked and found out in fact my F.I.L. tore it all out. But one of the main things I remember
was that the carpet was saturated with water. One give away that it was
the same house was the fact that it was a flat roof- one of the few in our town. The house was built in the early 1800's,it was a Finnish boarding house at one point, a butchers shop, and at one point, a survivor from the Titanic lived there. But all that was there of the house at this point were
the inside wall structures and the frame, but the wood was all new-looking.
I've thought about going back to try to find out who this young lady is, but
due to all the extra noise from outside, I can't get relaxed enough. This is one of the most dramatic, in depth dreams I've had,thus far. Also was in color.
