Wow that was amazing experience you had there. I live in Norway and of course we get the northern lights too but mostly in the very north. I live in the west so we only get them on rare occaisions when it is very very cold.
I so understand you about feeling connected to the universe when you are out in the nature. In fact it has recently been scientifically proven that our bodies receive some kind of positive energy from trees and this can improve health enormously. Im with you in that one.
