The way you feel about your dream is very similar to how I feel about the tornado. It's something that's supposed to be huge and overwhelming and horrifying, but instead it leaves a positive effect. I know it sounds strange, but the tornado passing me over actually made me stop having recurrent suicidal thoughts. A lot of people describe storms as "angry", which I can definitely understand, especially if it destroys everything you love. But I don't think they are angry – I think they are just so astronomically powerful that they cannot help but destroy anything in their path, because humans and everything we build are miniscule in comparison.
I'm not sure how to describe my new view on spirituality, but it certainly feels different. I feel much more connected to the world around me, especially nature. I am less in my own head and I feel less like a solitary person with the world existing around me – I now feel more like I am one of many living with a world much bigger than I am and much more powerful than I could ever understand, but it is comforting in a way I don't quite know how to describe.
