Nightmares about facing your worst fears?

I had a nightmare. I was with my wife and her parents at a fair/carnival thing. And my father-in-law Kevin pointed out this area with a giant sign that said “STEP RIGHT UP AND FACE YOUR FEARS!” I said no but he grabbed my arm and forced me to go. Next thing I know my father in law and I are up in an airplane (I’m deathly afraid of heights), and they’re all telling me to jump. I ask Kevin if he’s coming with me he’s like “I’m not the one who’s afraid of heights” and he pushes me out of the airplane. Then 3 different endings play. One of them I land safely, the other two I crash and die. Anyway when I get back on the ground then I’m like ok it’s over, but then Kevin makes me go back over and over again. They do everything to me from shackling me to the floor and covering me with cockroaches and snakes (both of which I’m terrified of), the next time they strap me to a chair and have a guy who looks a lot like Freddy Krueger keep jump scaring me and gruesomely cutting parts of my body off(which is why I hate horror movies) then they set me on fire, electrocute me, torture me to an inch of my life (my biggest fear is death) the whole time my wife and her parents are watching this and laughing at me. I ask them why they’re doing this they say “So you will stop being such a wimp all the time”... then I woke up. Does anyone know what this dream means??? I can’t do these things in real life. Could there be another meaning to this? Please help!
