What does my dream mean? A friend died in it-I need analysis!?

[M]

Last night I had a dream where my kind of old friend died. I just graduated high school, (she was in my grade) and we used to be best friends/in the same friend group way back in 8th and 9th grade. We grew apart a little, (no hard feelings AT ALL) but we've remained distant friends throughout high school and we've hung out recently.

In my dream, there was one day where her, a couple of our friends, and myself hung out tubing in a dark almost sewer-like place. It was odd but we had fun and I didn't feel scared or anything. The next day in my dream, she had died and we were all at her funeral. It wasn't sad or depressing though. The church we were in was all white with a lot of big windows with a lot of light shining in. No one was sad or crying, (I guess celebrating her life??) and I thought I should be crying but I was just overwhelmed with shock since I hung out with her the previous day in the dream. The church was full of people in light colored clothing and there were quite a few people from our graduating class there. The girls from our old friend group talked about letting something from behind, where the casket and priest were, shine through them and make their eyes and mouth glow. The dream (or maybe second dream?) ended with my now best friends cat at my house eating cat food where my old cat always ate before he got sick and passed away.

Other info that might be important: The day before the night I had the dream, I was cropping a picture of me and the friend who died. I cropped her out of it because I wanted just me for a profile picture on Twitter. It was of her and I on a beach (sunny day) at our senior class picnic.

Please help me analyze this! What does the dream mean? What's it telling me? It probably isn't important and it's just signifying change in my life, but I want to know for sure. I still care about that friend and I don't want her to die in real life! Lol sorry if this story seems strange. Give me your analysis please!

Dreams of death doesn't mean, death in the literal sense.

Dreams of death mean a change, in your case it most likely means a change in your relationship with her.

What that change will be, no one knows.
