Sarah,
I have had a few experiences, exactly as you describe (without the waving arms!) it is usually between 2 and 4 am when i have got back into bed. I kinda have this feeling that I am not going to go back to sleep and have a mild expectation of something. I used to be frustrated about not being able to sleep, but now if I feel like that realise there is another option. So being relaxed helps. I usually do go back to sleep, if I need to, but if not then stay focused and breath deeply and the very first thing I feel is a vibration like you described. At first it comes in waves from my head to toe, then is just there. I too once noticed I can be too much of an observer so do not progress further, but If I stay "in it" I can feel a separation starting to occur. I will then get out completely of or have this balloon on string feeling. Separate, but still attached by a thread. This has happened 3-4 times in the last year and only twice did I separate completely. I can get the vibrations quite easily.
So the vibrations do seem to be the start of it.
