Dream About Desert Mechs Battle

Last thing I remember was being in a desert like area in the backyard of my mom's house (different from their current house) they had some clock that was going off and I was looking around like where is that coming from and when I found it I actually woke up to here the church bells were ringing and that's what I was actually hearing. It was like a videogame for the rest of it. We had these gian mechs that looked like dogs kinda and we were attacking other smaller mechanics and I was watching my friend playing this from his perspective but it felt like I was just in his characters body watching. He lost his mech in a battle and was trying to escape in a giant hoarde of enemies. He only had a few bullets in his handgun which was not strong enough to take down these mechs. I remember being scared thinking I would run if I were him bc he's got no chance of winning like this.
