Respectfully, within almost any context, jumping out a window, going over a fence, and flipping a neighbor's circuit breaker on and off would qualify as irrational, not to mention, potentially dangerous. The neighbors were allegedly bothered enough to call police. I am not a fan of The DM at all, but I think most people would agree that it seems apparent that, at least at that time, Heidi was having mental issues. People who are just 'feisty' do not usually voluntarily check themselves into psychiatric facilities. Now, that in no way means that she was still having mental issues at the time of her disappearance, but I do think that possibility has to be considered. She very possibly was under a great deal of stress at the time of her disappearance, and even the strongest of people have breaking points. JMO
