Does anyone happen to know anything about the etheric, what it means to us too?

Had a couple of OBE's i've posted in this section of the forum. I'm adding to that in a way... Basically not so long ago i saw something from my brother which was pretty different. Not too sure if there is another explination behind this or not but I felt his time in a way. What I saw was his etheric body ahead of time, noticing a nice rainbow effect between physical and emotional. Not too sure what this would mean to someone but thats about it.

Thanks.
