I remember having similar experiences as a child. What's strange to think about is; what if we lived in a world where we all had this symptom and just considered it normal? The intersection of "reality" and perception is a fascicnating place
After a long walk, I often have the experience of standing still on pavement, and watching the paving continually expand away from me.
Obviously a simple example of fatigue of neurons encoding one perceptual quality enabling the over expression/perception of its opposite. But it just demonstrates how fragile our conscious perceptions are to every day minor sensory/perception deviations from their nominal correspondence.
After/during a traumatic experience, my mind disassociated from a basic aspect of reality. I knew what I perceived was completely nonsensical and misleading, but that didn't attenuate the very dramatic and warped perception in the slightest, for months.
