I can feel myself start to AP, but it never fully happens

For the past few nights i've been trying to AP. I have gotten extremely close almost every time. First i feel the vibrations, then my ears ring, i feel like im floating, my heart races, and my body feels like its moving side so side as if im on a boat in a storm. I try to just allow it to happen, but after a few minutes it stops and im back to nothing. I also cant get my mind out of my own body, i feel myself lifting but my mind feels lower than the rest of my body. i get distracting thoughts that take away from my focus, but i can never shut them off.

I also have trouble visualizing myself. I will visualize myself as different random people automatically and not on purpose. Of course i know what i look like and everything but I have trouble actually seeing myself.

if anyone can help me with this so i can fully astral project it would be much appreciated, thanks!
