Do you think people become like angels when they die?

I mean before Jesus comes back again, and the dead are in rest. What sort of jobs do they have? Do they see us? Do they guard us? Look after us? I believe in the Bible, but the Bible never says what exactly happens before Jesus makes the new heaven and new earth. I do not think we are floating around playing little harps, that would be boring.

What do you think happens? What do you imagine happening?
