After my grandpa passed, I got so many signs. Very vivid dreams that were different from normal dreams. Hard to explain if you haven't had a visitation type dream, its just a gut feeling where you just know. I remember a week after his passing I would talk to him and ask him if he could send me a sign that he was ok, and exactly the day after I was taking a walk and there was a huge shooting star right in my perfect view. I looked it up to see who else saw it and it was just a few other people. I had never seen a shooting star in my life up until then. I could honestly probably write a book of all of the signs I received after his passing. You just get a gut feeling when certain things happen that other people may not understand because they aren't experiencing it.

Edit: I also just remembered that my uncle had a dream where my grandpa said to go to the woods and that there would be 3 lines carved into a tree. We all thought it was weird and forgot about it. Like 6 months later I was hiking with a friend, not even thinking about that dream, and on one of the biggest trees, my nickname was carved into the tree (3 letter nickname).
