Voices In My Head At Night

For the past few months I have been experiencing something I can't explain. I lay down to sleep and relax, and then it starts, I hear voices in my head. They aren't talking directly to me although I think a few times something has been directed to me but to be honest it's all a blur when I try to remember. The best way I can describe what I'm hearing is bits and pieces of conversations, I don't get to hear the full conversation just a small part and then it switches to a different one, often different people but it seems consistent that all I hear is women. At first I tuned it out and the next few times it happened to me I let it run and the convos just kept skipping through endlessly. Last night I tried to focus and listen but I didn't hear anything, I feel I was trying too hard and not relaxed enough. What is happening to me? And if this is indeed a psychic ability how can I develop it more and understand what it all means. I have had abnormal experiences happen to me before, quick example: when I was 15 I had a dream of a hospital, 2 stories high and driving past it and seeing a white like fog leaving a window. I shared with both my grandmother and mother at the time and they both believed it was about my grandfather who was I'll at the time. A year later my mother was diagnosed with cancer and passed away, but here are the details. Before she passed away she was transferred to a hospital at a different town hours away that id never been to, she was transferred first and then I followed hours later. We drove past the hospital and I was shocked... This was the exact hospital in my dream and she was on the second floor. She passed away a few minutes prior to my arrival. Which leads me to believe maybe I'm more sensitive than most people to this kind of stuff. I'm a bit clueless and have no one to talk to about this and feel very lost and confused.

I don't know if this matters or not but I'm 25 years old.
