my very first astral projection

hello, today i had my very first astral projection, although it felt like i have done this before many times and not being aware that i am projecting, what happened was that i meditated before going to bed for about 30 minutes, then tried to keep my mind awake while letting my body sleep, it all went dark for a minute and i woke up at my workplace, my vision was weird it was as if i was looking at it through a white window, i couldn't see any cord/rope coming out of my body as people describe all the time, i was able to fly for maybe 3 feet off the floor? so all i did was just fly around my workplace as it was too hard for me to go further or it felt like i was restricted, my alarm went off and i woke up, but i went back to sleep after turning it off and woke up in my workplace again in the same spot that i left at. it felt weird as i was there for maybe 3 minutes then woke up again and went to sleep again waking up in my "dream". any ideas of whats going on?
