Am I doing this right?

So last night I was trying to Astral project (I am a beginner in this, I haven't had any OBEs yet), I relaxed, layed down on my bed, relaxed, and closed my eyes.I tried a few different techniques for about 15 minutes, but to no avail. I then decided to open my eyes for a second, at which I started to feel a sort of tingly floating feeling accompanied by a sort of binural beat tone playing in my head. It started to die down,so I tried to separate by the action of getting up, and I just got up physically. What am I supposed to do next? I feel like I'm pretty close.
