Dream: 7th Floor Apartment with MP

I was moving into a building apartment which I did not realize until late that MP was also residing across my room.  After moving in and everything was all in place, I left the room to throw away the trash and empty boxes. While outside my room in the hallway, I could not remember my room number because the doors are so identical.  Totally, I was lost but has the ability to see through inside the rooms and able to scan through the window and able to see the outside for markers like trees or building.  In my hand was the room key holder with a coin and a slightly visible inscription of a room number which is barely visible but I could not make up the number.  The key holder did not have a key, I was so focused in finding my room.  When I scanned the inner room, I noticed a familiar face [MP], she was lying in bed reading a book and when I gazed at her, it was the same look and youthful face that I saw during our very last goodbye 27 years ago and then I woke up and wrote this entry.
