Can someone tell me wur my dream means?

I'm a freshman and I'm male And I had a dream tht there was a war and on the opposing side was my bestfriend tht moved to new Mexico in 4th grade. He joined our side and we were constantly afraid of his side coming to get him. Then big tanks riled over my neighborhood (where we were) and it was my friends side coming. Then I t ended and I woke up tense andy heart was going fast. Me and my friend were like brothers growing up. Pleases only serious answers.
