My husband has an active dream life, as do I. But he's never had a dream that he recalls about Sasquatch. (Nor has he seen one.) But this happened: the same night I was listening to a Coast to Coast program with Darcy Weir (http://www.occultjourneys.com), which my spouse did not know I was listening to -- he had an intense dream about a Bigfoot.
He told me the Bigfoot was a good eight to nine feet tall. Scary, incredible, and the BF came across the water. Wading, up to his waist, across the water. Plus, Jim dreamt he was a woman. He/she and others were watching the Sasquatch come across the water, towards them. The BF was scary, they were hiding as they watched the Sasquatch being ripped apart people. Jim did not know why the BF was doing this.
No, I don't think this is any magic demonic omen. Simply an interesting bit of synchronicity regarding images and timing.
