Was I Astral Projecting?

Hi their! Yesterday i was reasearching all diffrent kinds of stuff about Astral Projection. I went to bed then I woke up about 2:30 this morning due to having a nightmare. I went to go get some water then layed down for bed again. But this time instead of falling asleep i felt weird and herd this buzzing noise. I remember hearing about this. After that noise i was like "Oh maybe i can try the rope techinuque." I did try it and i coulden't see anything but blackness but i could feel the rope and i got my head up and my hands up. I could also feel my physical body while doing this just lay their. It made got me kidna feel like i was paralyezed. Then all of a sudden i got scared of somthing. It must of been because of my nightmare i had so i told myself to go back to my body and i woke up afterwards. Is this astral projecting? I just wana make sure it is.
