Yeah it's perfectly normal to have dreams that don't make any sense at all, at least not at the surface. I tend to believe that dreams are, to a degree, manifestations of ourselves and our primal instincts. It's not always easy to decipher the meaning behind them, and sometimes there might not be a meaning.

I recommend trying a WBTB before attempting a WILD, and also try reading KingYoshi's WILD technique.
