Dream About Mysterious Mirror In Forest

This dream was about

I saw a huge mirror in the midst of a forest, turns out I was camping with a group of several people and was playing with ball with two people near camp. One was a tall Asian man perhaps a Korean I guess named hijesama and another was a girl whose legs seemed very weak so she was using a pair of crutches. While we were playing due to a hard throw suddenly the ball goes abit far from the camp so I decide to go there to bring the ball back. When I found the ball i noticed that I was experiencing some weird vibrations but I thought it's just because of a sunny day and due to tiredness that my ear might be ringing. As I was lost into my thoughts hijesama and the girl with weak legs reached me from behind and surprised me, they asked me why I was taking so long to bring the ball, I said I don't know I just started feeling weird so they started looking around and as hijesama was a very tall person compared to me and the girl with weak legs he said he could see something in a distant area but he couldn't exactly identify what it is. So three of us decide to go towards it. On the way I took the phone out of my pocket and noticed it wasn't working so well and started lagging. I thought it's just usual problem that I have with my phone so we kept going on. As we got near hijesama could see that it's a very big object so he started walking faster in curiosity, as we got more near me and the girl with weak legs could also see it. It was beside a small uphill so we approached it from side rather than top. We were surprised to see that it was very big mirror with golden frame which was rectangular but curvy at the top, as we approached it from side we weren't exactly infront of it. Suddenly I remember and tell hijesama that I have seen something like a video in internet long time ago about such big mirrors in random places but I don't remember the details. Then hijesama expresses that he knows about the video too. And then we decide to search up about it internet so I open my phone just to notice that it's brightness was at it's lowest and was almost impossible to see especially as it was a sunny day. So I tried to slowly increase the brightness but in shock noticed that it was decreasing back to low automatically, even after several attempts the phone was acting same and even started lagging. All three of us were shocked by seeing this, so the girl with weak legs says that we should head back to camp and come here with the entire group later. I agree with her and tell hijesama let's go back this place doesn't seems right. The vibrations started increasing and all three of us could clearly experience it, I keep saying hijesama let's get out of here..! But he kind of wasn't responding like he was just froze in the moment and can't stop glaring at the mirror even if we were not infront of it. Suddenly I see that the girl with weak legs starts panting and running as fast as she can even with her weak legs. So I pull hijesama once but he doesn't responds so I start running too, and I hear a creepy voice saying the boy will be with me. I was so panicked that I didn't even look back or anywhere, i just kept running until I reached camp in a completely sweaty state. My body was burning hot so I grabbed a water bottle and completely finished it then I started looking for the girl with weak legs in camp tents but she was nowhere to be seen, i understood that she fell somewhere by probably tripping over by a rock or something. But I didn't have enough guts to go looking for her alone. Then i scream everyone to gather together but very less people notice and respond. Then i started looking for a alarm which we had for emergencies, turns out it was buried in soil so I grabbed a shovel and started digging just to see that it's not there. A guy chilling on a chair nearby told that it has already been extracted from the soil but not used yet and tells about the guy who has it i quickly grab it from the guy and press it, this time everyone looks towards me as it was a very loud noise so everyone started gathering. We decide sitting in a large king size tent and held a meeting. I was telling everyone what happened and I got snapped out of my dream. After waking up i noticed I was actually in a sweaty state and was panting.
