Spinning sensation during meditation? This other day I was meditating and I got a feeling as if I spinned around on an axis, counterclockwise wise and really fast. Later on it became more of a left>right feeling alternating feeling in short bursts, and eventually it subsided.

What is this? Is it a sign of progress?
What is this?


It's merely a feeling. Just note it, observe its characteristics and return to the primary object. If you get attached or interested in it, then note that and take it as an object. Then move back to the primary object. 

In Vipassana meditation one treats every object equally.


  Is it a sign of progress?


Yes, ie. if you were mindful during the processes of the object, not after or later, but while they were happening.

You noticed it proceeded in bursts, meaning its not permanent but ever-changing. You noticed that it eventually subsided meaning you saw (if you were mindful of it) that it was subject to cessation and uncontrollability.

Whether you saw these things, I cannot know, only you can know. But if you saw these characteristics, you have seen the Three Marks of Existence, which all compounded phenomena are subject to.
