Unsure if I did astral project...

hello! I’m new here. This happened a long time ago, but one day I was meditating at night and I was laying down. I’m not sure how long I was meditating because I usually do it to fall asleep. At some point I noticed I wasn’t breathing and then I felt myself get pulled very quickly downwards into my bed. I had so many weird sensations and my eyes were closed but I could see my bed from below and everything had a purple tint. It only lasted for a few seconds. I did this many times over months trying to make it last for longer but it only ever lasts for a few seconds. I can’t even explain the sensations except it was like my whole body was tingling and vibrating while being completely still and being sucked downwards. It’s so shocking when it happens and almost feels like the worst rollercoaster ride ever. Am I astral projecting without realizing it? That’s the only thing that the internet points me to.
