ah, i often have false awakenings to, as a matter of fact, i don't like them at all.
in most cases when i have false awakenings i just lie in my bed thinking about what i've been dreaming planning how i should jot it down in my journal and i've noticed that it often interferes with what i've actually dreamt.
sometimes i wake up and remember all kinds of stuf so i start writing my dream down and after a while, when i reach the point of the false awakening, i notice that i've already written parts of that dream down in the "real" dream before that.
but when i manage to keep these dreams apart i actually enjoy this phenomenon.
other than that i often panic in my false awakenings since i'm always late for school or something like that.
