What you're describing is the sensation of your astral body separating from your physical body. It's frequency/vibration is increasing to allow the separation to occur. First time it happened to me I was scared out of my mind. Read the story here.
What you want to do is once you get to the end of the tingling sensation, try lifting your arms out of your body. You probably were experiencing dual consciousness as well, which is when your physical eyes are closed but you can see with your astral eyes. You can feel your physical eyes are closed but you can still see.
It's really rare to even get to the tingling phase so consider yourself blessed and try projecting
try not to be scared.
