How to proceed?

Last night I was laying in bed, after returning to my body from what I believe was astral projection. All of sudden, I feel as if my body is starting to rise. At the time, I have full control of my thoughts, but I didn't try moving at all. I started to hear a rushing sound in my ears, kind of like a very powerful fan. There did seem to be a light vibration.

I wasn't sure how to proceed. I tried imagining a meadow, but nothing happened. I tried picturing my hands as well, but nothing happened. A weird noise startled me. I tried staying in this state, but the source of what made this noise bothered me, so I willed myself out of it.

I am wondering what I should do next time I'm in this state? This happened to me a month ago, but I got scared that time and didn't allow it.

I've never actually astral projected, but the few times I was able to WILD I always felt intense fear grip me, the fear seemed to rip me out of my current state of consciousness and it literally felt like I had been catapulted into and through a void, then I landed in a dream.

So for me, I use the fear as a tool, It has been a long time since I successfully Wilded, so I don't remember the exact process, I just remember that fear was a sign I was doing something right and should continue, so when you willed yourself out of it, you were almost there I think.

Courage is the key maybe? the ability to feel fear, but not care? it seems so for me anyway.

The best thing to do is simply wait. As soon as the vibrations and noises stop, you can step (or roll, levitate,etc.) out of your body.
I'm not that experienced myself but after astral projecting a few times, the noises and vibrations disappeared.

If it were me, the first thing I'd do, before deciding not to care about the fear, is try to understand better what's inspiring it. As often as not, fear is an indication of something dangerous or unhealthy that's worth avoiding.

The first time I astral projected I felt afraid, but the fear wasn't very intense, and mostly it was fear of the unexpectedness and unfamiliarity of the experience and not being sure I could get back in my body. I was also afraid of the spooky stuff I could see and hear, but I feel that stuff is there all the time anyway whether I'm paying attention to it and making images out of it or not, so I don't see the point of being afraid of it. Maybe your fear is about something else though, since the experience of it sounds different.

Some people think that repeated astral projection is unhealthy, that it cultivates a dissociation between the astral and physical bodies, which eventually leads to physical and mental health problems. That view seems plausible to me, though it also seems to me that the astral body isn't real in quite the same sense that is sometimes assumed. My rule of thumb would be to do what seems to feel healthy, and not do what seems forced or icky.
