Dream About Losing Belongings In A Quest

I was in an auditorium with my school and my classmates but I don’t think I actually recognize any of them in my real life. There were quests and stuff I had to go on and I had my school backpack that I would leave in my seat as I would go on these quests. I don’t even remember what these quests are or much else about this dream but I remember this old lady had died or we at least thought she died but I think she turned up later in a different dimension or something but to mourn her loss everyone dressed up as her and drew her on their forehead and it was this weird cult like thing. Then it was back to the auditorium and I was trying to find socks cause I guess I lost mine in the last quest which I think is where I found the old lady that they thought was dead. I couldn’t find a matching pair in the shit ton of things I had in my backpack but the people next to me were offering me their packed socks. Then the girl next to me was looking through my bag and kept pointing stuff out and was just like taking it all out not putting it back, and I had my iPad doing homework while she was doing this but then all of a sudden the ground started shaking and the people running the assembly yelled that we were all in danger and to run. And then I was upset cuz all my stuff wasn’t in my backpack but I wanted my stuff but in scenarios like this you’re just supposed to leave your stuff. But I grabbed my backpack at least what was left in it which I don’t think was much mostly just my computer and I ran. I think we all waited outside of the auditorium at that point and I was just thinking about how I could’ve had those extra clothes had that girl not gone through my bag and also that I should’ve grabbed my iPad too.
