Sosick, I've been getting similar dreams. Going on for a time now, probably a few months. Just vivid and wild and they go on all night till I wake. Doesn't feel right and is usually a sign (for me) that things are not well. I must admit, it's happened before in the past when I've been sicker than normal and it's occured again since my last dental visit where no doubt I've been exposed further to the toxins of dentistry (anaesthetic and all that).
