Room with infinite doors?

[Merro]

I had a dream this morning. I was at school and I had to go to the bathroom. I went to the school's restroom and when I got there I was looking at the mirror. Then when I finished washing my hands I tried to open the door that lead me out of the bathroom. I opened the door and it brought me to another bathroom. I was thinking. What the hell is going on with this picture? A room with no way out? So I walked into the bathroom where the door lead me to. I saw another door. I tried to open that. And it brought me to another bathroom. I kept doing this for 10 minutes or so. When I got to the last door. The door had lead me into an empty room. The room was empty and the room was yellow. The room was also big. It had couches and stuff. The room had doors on the walls. I was saying to my self. Oh great more doors. I wonder where they will lead me... If I picked the right door. It would lead me into waking up. If I picked the wrong door. It would lead me into a nightmare. If I picked another door. Something odd will happen. Then I saw a girl standing in the middle of the room looking at me funny. One of the girls I knew from my old school. I was asking her why is she here? Then she ignored me and walked around. She walked into one of the doors and she was gone. I opened the door she was in and nothing was there. There was nothing but a wall. I tried to get out of the room. I started feeling panicky a little bit. But I stopped since feeling a panic emotion will probably get you into a nightmare. When I was in the bathrooms with the infinite doors. I was hoping something would be waiting for me there. But nothing was there. All there was was doors that kept leading me into the same room. Until I found that door that lead me into the yellow room like I mentioned. I woke up thinking. What the fuck just happened? Anyone know what could make this dream happen? Doors that kept leading into the same room. It's all crazy.
