Trapped in a burning Building with shifting Doors

"I was trapped inside a building that was on fire. I don't remember how the fire started. I was in a room looking for a way out, but every door seemed to lead somewhere different. One door opened into my kitchen, even though I knew I was supposed to be upstairs. The smoke wasn't thick at first, but it kept getting harder to breathe. I tried opening a window, but it was stuck. My hands felt strangely weak and I couldn't get enough strength to push it. Then suddenly I was in a hallway with flames behind me. I could hear someone calling my name, but I couldn't tell where the voice was coming from. I started running, but my legs felt heavy, like I was moving through water. I reached a door and pulled it open. Instead of outside, there was a quiet bedroom on the other side. I remember thinking this made no sense, but I went in anyway. Then I woke up gasping for air, with my heart pounding."
