I'm blinded when I astral project.

It seems like I've been able to get near the out of body state at least once. The first time it happened, I realized I was paralyzed and my body started vibrating. I then heard growling near my ear and I was so frightened because I couldn't see anything and I couldn't move at all. When I finally did come out of my body I was uncontrollably spinning around the ceiling and bumping into the walls and such. I remember being really scared and tried really really reallly hard to wake up. Now I'm really curious about Astral travel and I would like to get better at it but it seems like I chicken out as I notice the paralysis starting :c. I've noticed that when I have had OBEs I've never been able to see anything, it's like I'm without my sense of sight but I have all my other senses..  it's like I'm blinded. Is this normal? I've only had a few experiences so far and I've never gone farther than my room because I don't know how to control myself. Most of the time I'm just focusing on getting back to my body. Is there anything that will help me control my movements and allow me to see?
