I had this interesting experience/dream last year, and it is probably the closest thing/experience that I ever had to astral projection or an out-of-body experience, and it is an example of how I sometimes dream about what I am hearing in the real world as I sleep. 🙂
The beginning is unclear and I am not sure if I was dreaming or if I had just woken up, I just remember laying in bed in my dark bedroom and I started feeling myself float from my body but my body seemed to probably still be in bed.
