This is not a dream, but something happened to me today. I heard sirens that wasn’t there. Between the hours of 1-2 a.m. I had laid down to go to sleep, and as I was lying there, I could hear sirens. I sat up because I thought some type of emergency vehicle was coming, but it wasn’t. Later on, that day I continued to hear sirens. As I mentioned this was not a dream but something that happened while I was awake. Can someone please explain what this means and why was it happening.
