Am I experience HH?

[yj1214]

Ok, so im going to wirte this quick. When I relaxed my body and getting sleepy, (like 10 minutes later) My mind starts to make thoughts, at first, it feels like low quality video, then it gets stronger and I could hear sounds too, then I'm getting more sleepy so I usually fall sleep. I never felt vibration or falling. Is this HH or am I just falling sleep in relaxation. Thank you
