Dream About Basketball Arena Entity

My two closest friends and I went to a basketball stadium with the normal crowd and concessions in the lobby area. We then snuck past the ticket stand to try and watch the game for free and had to go up some stairs, once up and onto the main court floor we start to notice that there was no one in the halls outside of the basketball court which is odd in real life. But we didn't think much of it and assumed that everyone must be inside watching the game so we entered the first court, we heard cheering but no crowd of fans and we can hear the basketball bouncing and shoes squeaking on the court floor but no players and the score board was on but no points were on it. We were creeped out at first but being the curious teen boys we were, we went and decided to go down to the court since no one was there to stop us and as soon as our feet touched the basketball court... it all went silent. There was no longer sounds of players or fans, no signs of anything or anyone. So we just shrugged it off and went to look around and saw some stairs that went up and down, we thought it was weird that there would be a second floor in a basketball arena. Once on the second floor we noticed that the court was the exact same as the first court we went to so we went back to the stairs and were surprised again to see that the stairs still went up and so we went up, the same thing happened so we decided to just leave but no matter how many flights of stairs we descended we couldn't get back to the bottom where the lobby was. We then decided to split up and look for a employee or a alternate exit, my friend mike continued down the stairs and luke went around on the outside of the court and i went to look for doors. After a few minutes i find a maintenance door that opened to a hall that look impossible to fit in this building normally, i entered this hall and walked through it and noticed that the same exact pipe or warning sign and began thinking i wasn't making it anywhere so i exited the maintenance hall and started looking for my friends again. As i looked for them i freeze and spot someone that looks like a security guard and then felt relieved, i yell after him and approach him from behind but then IT turned around to reveal that the security guard didn't have any facial features. I stop again out of shock making sure that im not seeing stuff before the security guard started yelling " halt! No one should be on the premises after hours! You're trespassing! Halt!" And started sprinting full speed at me repeating his warnings so instinctively i ran from the security figure not liking the feeling it gave me. I ran and ran in circles it felt around the arena looking for any escape from the inhumanly fast entity, i ended up making a turn towards the stairs and slam into mike coming out of the stairs hall. I try lifting him and pulling him with me but he pulls back and asks me "what's wrong?" And at that moment I realize that the security figure was not chasing anymore. I explain to him that a security thing was just chasing me and before i could tell him how it looked, mike says " well why did you run? You could have let him kick us out because it seems impossible." And then i tell him the important details about the security guard entity not having any facial features and was faster than ive ever seen a security guard move and then he believed me because of how odd and eerie the place was. We then go and look for luke to make sure he is safe, once we find him we fill him in and he tells us that he also was chased by this entity. Freaked out by this point, we all stayed together knowing full well we can take on any adult no matter what size and went on looking for exits. We head back to the stairs before hearing loud footsteps that was obviously approaching fast and his voice was louder and more aggressive so we ran still. We ran to the stairs and for some reason, we immediately went down for real i to the lobby and slammed into the locked doors realizing we're trapped. We turn and get ready to fight head on but no one was there, we sigh in relief but we know that we still need to get out so we attempted to break the glass doors but they seemed unbreakable. Then we hear " hey! What are yall doin? You kids shouldn't be here at this hour" and we turn to see a normal security guard with normal features and a surprisingly lax and friendly attitude. We just stood there unsure to trust but he looked creeped out by us and said that he will have to remove us and unlocked the door and he interrogated us about how we got in the basketball arena in the first place as if we entered when it was closed when we obviously didn't. We dont tell him the truth but tell him that we were just being stupid and wanted to sneak in for fun and he laughed and said " kids, always finding something crazy for fun" and let us off with a warning and once outside i sigh and say "that was crazy, right?" And then my two friends that were with me acted as if they had no clue at all what i was talking about. as if we didn't just have the creepiest experience ever and as soon as we get into my car, i wake up.
