And again, nothing might ever happen. The same time, it might be affecting the dimmer and you don't know about it. It over heats and starts to blink on filament lights, and that might be caused by using neons, fluorescents, etc. You won't see anything blow up and go down in flames, the issues are more likely to be unseen, your neons and fluorescents might burn out early, ghosting dimmers, or you might be very unlucky and have the things stop working.
Just as a general rule of thumb, don't plug things besides filament lights into dimmers.
