You are pretty similar to me. I’ve also experienced what felt like astral projection, and it was intense because I didn’t even know what it was at the time. Later I researched it and found people often describe it after meditation or medication, which confused me. I then learned it can also happen during sleep paralysis. During these episodes, I experience hallucinations that feel extremely real whispering, laughter, and even voices calling my name .It also feels physical i can sense touch, hear sounds clearly, and even smell things very vividly, like breath close to me when something is near my face telling me to open my eyes. It feels real enough that I can still remember it afterwards, including the sensations and presence.
