do آپ think that your dreams and thoughts exist in your own personal physicial realm where آپ will exist once your body is no more...

No, but it's an interesting point. :)

It makes sense in some ways, because in physics energy always has to be transferred - it doesn't just vanish. I've never understood what happens to dead people's energy - it has to go somewhere!

I guess we won't know until we die........

I've thought that myself but I honestly don't really think so.
