Solipsism dream interpretation help

I have a recurring day-dream, or more of a recurring thought that I am not really existing in my current or perceived reality. I have the constant thought that I could at any time wake up in a hospital bed, awakening from a coma. In this daydream, my entire reality and 23 year old life has been a dream that happened in my mind in the blink of an eye of actual time. In this dream, I often perceive myself as being "inside" myself, or "below", almost as if I am existing in my stomach, and I look up to my "actual" self lying in a hospital bed. Perhaps this could mean I feel like I am not living to my true purpose? Or that I am trapped inside my own mind?
