I had these dreams for several years. I carried and shot IDPA now and then. I read Dave Grossman's book, "On Combat", he says these dreams are the result of performance anxiety and can be combated by practice and preparation. Soon after reading his book I practiced an am now at the expert level in IDPA, training to make Master at the next classifier. No dreams since I started routine practice a year or so ago.
It worked for me. I recommend his book to all.
