last night while meditating with the mantra I AM, I got this weird spinning sensation, it seemed like my whole head was spinning inside, and at one point it seemed a little nauseating. A while ago I wanted to get into meditation and i moved the energy from my toes to my head and got this bad spinning sensation when the energy got to the top of my body, its like being really drunk and the room is spinning when you close your eyes. I figured I shouldn't mess with energy like that and then someone recommended this website so I stopped doing that and found this website which started me on the I AM mantra which seems to be working. Last night was the first night that I had the spinning sensation since. Has this happened to anyone before, and why does it happen to me.
Nearly all symptoms of this kind are due to purification going on in the nervous system.
This is nothing to worry about at all in fact it means you are doing things right, when you become aware of uncomfortable sensations like this just let your attention rest on them for a few seconds and they should go away.
If dizziness persists after meditation then you may need to cut back on your practices a little go down to say 10 minutes meditation and see if that helps.
You are obviously very enthusiastic about your practices and thats a good thing but remember its important to self pace
