Okay i just had the weirdest dream and it freaked me out but I don't understand...?

Okay so I was running and I was running down a road and It was windy and the sky was covers In clouds and had a Greyish orange color. I kept running till I came to a field were I griped and fell but I got back up and kept running. I then came to a wooden playground I played on as a kid. I stoped and looked around. I knew I was looking for somthing but I didn't know what. The winds began to pick up and I started running again and I ran and ran till I came to my friends house I ran in the door and ran up the steps and to her brothers room and 1 tear fell down my cheek. I ran back down the steps and outside were her brother stood at the bottom step he looked at me and I had stoped. I then walked quickly down the steps and he held his arms out and grabed me and I hugged him and we fell on the grass. We laid there and I stared into his eyes and a tear fell down his cheek and he had this like long distance look he always has in real life when I see him. Bu I had the same look in my eye I could tell. But what was really weird was threw the whole dream I could faintly hear the song "blessed with a curse." by bring me the horizon. It's an eerie song so that's partally what freaked me out. But it's also that its his favorite song. I woke up and my heart was racing. I have had like things with him In the past were we liked eachother but we haven't talked in forever but I saw him 2 weeks ago and he had been acting weird. Idk why but this dream really freaked me out. What did it like mean.. ? I have never been so confused about a dream before...
