Your problem here is that your astral is trying to fly from your body but your body is trying to keep tight hold. I suggest getting a tether. A simple white or silver cord, ribbon, rope and tie it around the wrist of your dominant hand. This will keep you tied to your body so you can move further away without any mishaps. -side note- The longer the cord the further you can travel.
