By the sounds of it your very close to doing an out of body experience which is just as good as a lucid dream....iv had an OBE before and i went through the same stage as you....i felt like i coukdnt move and waited for the vibrations to slightly ware off then i litrally got out of bed.
I then looked down and saw myself asleep in bed and from there i just flew out my bedroom window and had fun =)
