Lowered resting heart rate after a deep session

Hey guys, hope everyone is having a great day.

I've got a question for ya. Yesterday I had a particularly deep meditation session, much deeper than I typically have gotten. I came away with a very centered and peaceful feeling that I am deeply grateful for. However, since this experience my heart rate has been considerably lower at basically all times. Usually when I'm driving I'm sitting around 85 bpm but it never got above 64bpm yesterday. Same thing with resting, my resting heart rate is usually around 67 or 68 and it was down to 56bpm give or take. I certainly don't mind this, especially for health this is almost always a good sign, the feeling of calm is just a bit unsettling.

Has anyone else experienced this? It really felt like I had that meditative experience and it did (and still is) continuing to have a physical effect on me many hours after the fact.
