What is the meaning in a dream of crutches

I was in the neighbor hood I grew up in. I saw a old friend I saw myself riding a bike when I was younger. a bully from my childhood was walking with crutches. I was trying to protect 2 kids hitting the man with a iron skillet and he was trying to kill me with 2 hammers then he tunes them around to hit me with the claw part and I tried to talk him out of it and as he was going to kill me I woke up

I dreamed that my dad had to work late so didn't come home uintill later, then a couple days later I had to have a foot operation and I couldn't walk without crutches. While I was in the hospital some woman that was quite a bit younger than my dad was with my dad went into labor, my dad said that he was the father and that he was going to do everything for this woman and never leave her. So he went with her and didn't visit me once. Then I was in the car with my mum and sister and my mum asked if we knew when my dad could have had the affair with this woman and I said he worked late a couple days back. Then we were at my house in the kitchen and dad's new baby was with me. I didn't like it as my parents were arguing in the other room and decided to split up. My dad went with the new baby and the woman and me and my sister went with my mum.

I fell down the stairs and snapped my ankle at school. They couldn't call an ambulance. I had to use crutches that the lunch lady gave me and the nurse wrapped my ankle and then taped it. I went back to the cafeteria and two of my guy teachers followed me in like they were gonna yell at me or something, but there was a class in there so they left. My crutches were too short so I asked the lunch lady to make them taller.
