In a state of sleep paralysis you can open your astral eyes while still feelign your physical eyes closed.
To escape the confines of your body and go astral, instead of just lifting out of your body you can try the other technique where you imagine yourself outside your bedroom or on top of your roof (my favorite) and teleport your astral body there. It bypasses the body's efforts to keep its soul in the body. It requires a great deal of faith and will because you've got to move your astral body to a new location and believe it will actually get there.
