I get the vibrations - they start off slow and then usually build up and get really violent. One time i could feel parts of my body jerking up randomly wich made me come out of that state. Sometimes i hear a really loud roar or wooshing sound too and it feels like my bed is flying through the air fast.

I love going into SP, the feeling of vibration is so weird and relaxing in a way.I'm glad I dont get any hallucinations
