Hello new to the forum and having trouble with astral projection

Hello, I’ve experienced sleep paralysis before to the point of being able to see the room I was in vividly like I was peeking my strap head out of my physical body. I’ve attempted astral projecting quite a few times sporadically over the years, but more recently have been more focused and serious this past week in attempting an OBE. I’ve experienced he “Godhead” or hypnogogic state a few times and during that I’ve tried visualizing moving my hands and body to move out of my physical body. I’ve also attempted this using the rope technique. When I feel the vibrations and the frequency heightens a rush of energy happens and I allow it. I then feel my physical body rising up. My arms raise, my back arches and I feel the muscles on the back of my head along with facial muscles twitching as if seizing. I am completely concious during this and it stops once I move. Am I not really in sleep paralysis? This is after 30-40min. Of laying still and relaxing. Should I wait until after the vibrations to attempt an exit? I will keep practicing, but any help would be greatly appreciated as I would love to travel the astral realms!
