Astral projection

Many people say that astral projection is real and everyone has the ability to do it. I have given it a shot a few times without success. Im able to fully relax my body while keeping my mind active and focused but I am unable to leave my body. I concentrate on my breathing and I have tried shifting my awareness to my third eye area and “opening a door”. Sometimes I can get a sense of floating but never able to fully escape. Has anyone honestly been able to do this and if so how?
