how did my yard get here

I was standing outside a huge, 2 story, brand new home. A man was showing me the home, the last words I heard, I leave this home to you. The man said it is all yours now. I guess he was reading a will.

I walked into the house, to the right I saw a small enclosed patio porch.
I found a master bedroom, with a separate nursery attached. Everything was brand new, modern and luxurious. There were so many rooms. It was fun to go through them all and I found secret roms connected to other rooms.

I ventured out into a hallway it led to a lower level. I looked over the railing to the left was a bar, dance floor and huge cozy lounge area, like huge living room. To the right was a huge dining room.

I get down the stairs and get past the bar and lounge. There was another patio. Much larger than the upper level patio. It started out as part of the lounge then sprawled out. There was a grassy lawn, putting green, gardens, trees, fountains and even small creek.

I felt like I was outside. I got to the very edge I found I was still inside, I ran into a clear glass wall. I looked up and saw a glass dome. I turned around to see it all. I saw the 2 trees and a small creek running between them.

I noticed the 2 trees were cherry trees now this yard looked just like my old home where I grew up. It now was the yard of my old home. I looked outside to view the neighborhood, we were now in my old neighborhood. The dream started out in a new home neighborhood in a different town so I thought.

One freaky thing when I entered the entertainment and dinning area there were people there, strangers to me. I didn’t know anyone. I don’t know why there were strangers in my new home and the one who was showing me the house had no explanation. Just ignored them as if nothing was wrong.
