In Hinduism/Buddhism, they have a belief in the “subtle body”. This is like the “outline” of the body, it is the vehicle for consciousness/personality, it exists below the “gross body”. It has energy centers or chakras, such as the intellect, the heart, etc. (the Greeks actually had this idea, too, the soul being made of three parts). I think this view of the “soul” is the most true. It’s not quite as “ethereal” as the descriptions I hear for the Christian idea of a soul, sort of a substantial thing that is amorphous and without shape and doesn’t change (in icons sometimes it looks like a jewel).
Another thing I’ve read, frequently in near-death experiences, people describe having a body. Some blind people have reported having vision for the first time, and people with missing limbs often describe having a limb in that place. Sometimes the body appears very physical, other times it is ethereal. Some people don’t even know initially they are dead, everything feels real.
