How to Astral Project? Urgent!!?

My Friend, wanted me to Astral project with him and said that anyone can have an Out of Body Experience, if they know the basics of "Breathing", and are willing to spend couple of hours to relaxing, so I wanted to ask, that is it truly possible for someone like me to leave my body by just relaxing a couple or more hours and then flying away from my body to Astral Dimension. My Friend just said that anyone could do it. Thank You All For Your Answers And God Bless You!
