Sorry for your loss. I am not good at interpreting dreams. However my guess is you miss your friend and you wanted to say hello to them again. And you got to. (Higher admin)

I'm sorry for your loss. Often times I'll sometimes have a dream about a loved one I've had that has passed away, It'll always be a dream where I'm just spending time with them again, I like to believe that it's a visitation dream and that they're actually there just visiting me from heaven through my dream. Helps me cope with the loss when I have those dreams and feel like I still get to see them from time to time.
