Hey guys I need help with assault that happened.?

Ok guys, I need to know if I am going crazy or not. The other day I was walking down the street and this man yells out to me “hey you get over here” I was like what do you want. He said you don’t think I know who you are? I was like ya because I have never seen you before in my life. He was like ok professor, I know what you have been doing around this part of town. I was like what have I been doing on this side of town. He was like well what you have been doing is my wife. I was in disbelief and said sir you are surely mistaken. He said naw man you the one with that fancy bmw. I was like sir yes I do own a BMW but I can assure you that I am not the one that has been with your wife. Then he started screaming at me talking about how my kind has been holding his kind down for to long. I was like what does this have to do with me doing your wife? He then went crazy and was yelling about how I just admitted it and he was going to have his boys pay me a visit. Then he starts to demand money from me and starts slapping me along side the head. I ran into the store and called 9-11. But when the police arrived they were just as weird. They were like we know what you are doing on this side of town. I was like not the doing his wife thing again. They said naw man that does concern us but what does is all the crack you been slinging in that fancy BMW of yours. I was like what are you talking about. They were like oh ya man, we seen you just the other day slinging down on Maple and 3thd street. I proclaimed my innocence and they arrested me for assaulting the man who had just assaulted me. They said that there was witnesses that said I was the aggressor. I was like who? They were like old man Murphy. I said I did not see anybody standing around and I sure as heck did not see and old guy named Murphy watching. The said oh he knew it was you because of the fancy BMW you drive. They then took my hand cuff’s off after they had taken my wallet with my money. Then they said they better not see me no more and that you should have known to come down here and start trouble. Guys what is going on? Everyone seemed so convincing is it possible that I did all this and forgot. Was it a setup and they were all in on it? There are a million possible explanations but I need to know if I missed some important detail as to what happened. This was the strangest thing that has ever happened to me.
