The more fully the brain integrates these perceptual streams, the more connected you feel to those you are moving with. Neuroscientist and dancer Asaf Bachrach calls this the kinaesthetics of togetherness.

A sailor who reported a similar sensation with his sailboat concluded that is why people love their boats so much.
