Experiences Years After Uncle Passing

I've had a few paranormal experiences but this is a favorite and not scary and would like some insight on what you might think.

My great uncle passed away a few years ago now. He was more like a grandpa to me. I spent all of my summers since I was about 5 with them learning to ride horses and just enjoying the mountains. I stopped riding when I was around 16 because I had surgery on my neck and brain but still would go visit him when I got my car. I just started riding again.

I have only fond memories but there's one that sticks out the most from when he was living. We had packed up the horses to go run some cattle for his buddy and we were in his truck (which I own now) and he turned on the radio, which was a rare thing because we usually just talked.

Fast forward to a little while after his death. He'd come to me in dreams and I can still sometimes smell what he always smelt like (a sweet syrup/molasses and hay scent) when I drive the truck. And more recently the radio has been changing itself even in my work truck and I don't mean like going from 106. 1 fm to 106. 2 fm. I mean from 93. 1 fm to 55 am which is a local radio station that we'd listen to while we were riding or working in the barn.

I've also noticed I feel his presence when I work my horse or am I a riding lesson and when I think of selling my horse and giving up riding again. I have also had dreams about him and my grandma (memaw) (they were brother and sister-in-law's) visiting me I have noticed more frequently and I'd get the urge to call my great aunt.

I'd love to know what all this means. Like I said there have been other experiences I have encountered other than just with my memaw and uncle some which have startled me and that are completely unrelated.
