my two favorite ideas for what happens when you die:

First concept, you just wake up into your real self and realize that this life was all a dream. Your higher self is just a higher energy version of you and this entire life is just one dream. In fact all consciousness is just a layer of dreams separated by different energy levels.

Second concept, I got this one from reading Carlos Castaneda. Basically in his book his teacher don Juan says that they "see" when a person dies this is what happens. Death comes to them from their left side, death enters through the crack in your energy body in your stomach, the crack expands and your whole energy body slowly disintegrates. Your energy body shatters like a million tiny crystals and your entire energy, you entire lifes experience shatters up into "the eagle" (which is how this energy formation looks, like an eagle) which absorbs your energy and life experiences into the eagle, which is like the cosmic whole (or could be thought of like the "dao" in daoism). at that point your entire consciousness disintegrates and you have no separate self knowledge (that is of your self in this life) instead your awareness merges into the awareness of the eagle. Sorta like if you were a human, and became borg, your awarenss would be multi-dimensional...

To me both concepts are curious and interesting.
