ENTRAIN: vb — to adjust (an internal rhythm of an organism) so that it synchronizes with an external cycle, such as that of light and dark.
I can feel this effect with clients when we take an initial deep breath together, remotely or in person. This essentially 'entrains' us onto the same frequency.
Watch this wonderful example of (what I would call) — ENTRAINMENT! It's really precious...
