What to I do next...?

Okay, when I do LD, I see and feel here and there, but after 5 minutes I become completely aware of the dream I am seeing everything is beautiful, then that dream starts melting and everything goes black.My progress is such that I am still sleeping Now my sleep is not broken , many times I lose awareness in the black screen and a new dream starts.

In case of black screen, to create LD dream again, use command in mind or visualize...?
