it was about my sister...we're pretty close and good friends

I was in a mansion that had many rooms and long hallways
I saw my sister at the end of the hallway motioning me to come to a room
Everytime I came closer she got farther away
When I finally reached the room I looked inside and it was empty
She wasn't anywhere, even when I look in all the other rooms
The rooms looked like hotel rooms

I wasn't really worried, just anxious to find her and I didn't know why I wanted to find her....

Tell me what you think it meanss!!
