Have you ever had a spiritual experience?

I am not super religious but was just curious if anyone here has ever had a spiritual experience or something they believe was a sign from God. I think I experienced something a few years ago. My grandma passed away and she was the most loving person I have ever known. A few days after she died I was driving on the free way and thinking if heaven was real. I was thinking there has to be a heaven for people like her because she was just so giving and loving. Literally as that thought was ending a semi truck got in front of me and on the back of his truck was the verse in the bible in the pic I posted below. Anyone else here have any cool stories?
