When relaxing, it's common to feel that and any other number of sensations. However, don't focus too much on your body's sensations. Instead, try and focus on INNER sensations, like the images that start to appear behind your closed eyelids.

I get your feeing in my head, its like your astral head is escaping.
Keep on practicing, its rare that someone OBE/AP on the first time. It may take a month or a year untill you AP/OBE. Do not loose hope, keep practicing!
