Wow, that sounds interesting. I've been astral projecting for a while but kinda gave up on it. I think to know if you are astral projecting you'll actually feel the vibrational state prior (though there are stories where I hear people who AP without going through that stage; which makes it all the more confusing) besides that you must be conscious at least. Sorry if I'm not able to give suffice information or advice.
I also read other stories about people who mistakenly believe they AP'd but only had very vivid dreams. If you're able to go into more in-depth on your dream maybe I can help you.
Maybe tonight I'll put on some headphones and play guided AP meditation when I go to sleep tonight
