In my practice of meditation it occurred to me that as I observed my thoughts it seemed as though they have an angle and force (vector). Obviously this would be metaphorically speaking, but has anyone else while observing thoughts notice them come and go as if having a direction and force? For example, while sitting next to a street, staring straight ahead, and observing in your line of sight a car coming from the left and disappearing on the right, some traveling faster than others. This would be the closest example I have. It may have no meaning, but curious of any thoughts both philosophically and / or a sharing of experiences.
