I've had this happen to me before during meditation. How long were you meditating for? This is normally what starts up for me before I am getting ready to astral project. I've never successfully astral projected before, but I've meditated long enough to begin the process. It normally starts up with what you have described and then my whole body will start tingling, progressing into a strong vibration. Ill then start to hear a lous buzzing or ringing in my ears and it will seem as if I'm spinning. My hands will start to feel as if they are floating above where they were originally placed, and my feet will start to do the same. At this point I begin to feel as if my entire body is beginning to float upwards and Ill begin to get various flashes of images and hear voices which is normal in the transition but scares me and Ill begin to lose focus and lose it all together so I never fully end up astral projecting.

This is just my expierence, I've done this a few times but have never been fully successful in departing from my body. I suggest you research astral projection and see if the same occurences you've been expierencing are related to the process of astral projection.
