I had out of body dreams for years.
In meditation upon how I had out of body images of my own bod, I have run into ideas like the body exiting a fly (proving the theory that non-clinging or egoless states will give you enlightened sensibilities, or they ar enot encumbered with anonymouse klingers).
When I could see out of a high rise wall while just closing my eyes, my meditation evoked images of fine fibre produced and wired by cockraoches. Yukch!
Perhaps the experience that epileptics had ( and I have also had this problem) reflects a tiny third-entity form, which is acting like the persons" "personal telsat".
Or, I think we usually have an image interpreter, like a bird, fly, flower, or gems in rock areas.
