Dreams about dead person

My friend shot himself about a month ago n I’ve known him since the 1st grade, I’m 18 now. Well we texted sometimes but never really hung out or anything but i went to his viewing to see him n that’s it.. i couldn’t go to his funeral I didn’t have a ride.. but ever since I’ve gone n took him roses n stuff to his grave.. but ive been dreaming about him at least once a week he will be in my dream idk why 😭😭😭😭 it’s not that I don’t want him to it’s just crazy since We weren’t that close n stuff. I dream abt him like one last night i saw him in my dream n we just hugged for a while n another dream he was sitting on my bed smiling. That’s just some of the dreams I’ve had..
