It sounds like astral travel to me. I think it’s normal that emotions are muted, it seems like the emotional body, the part that is generated by hormones, stays behind with the physical at this stage of travel.
I’ve heard of really deep stated of travel were it’s so real if you get hurt there you can bring that hurt back.
The myth that if you die in a dream you die in real life may be true. But most usually the event wakes you up right before it happens. … meaning, there’s deeper travel where you bring most everything of yourself with you, but for most dreams you only get a bit going out there.
