When the real collapse occurs, what are some of the signs to be looking out for?

I mean, will it be a quick fall, or a slow one?

If slow, what are some of the things that will start showing up before the collapse, like inflation slowly going up, gas and oil prices start rising uncontrollably, devaluation of the dollar, bank loans stop, or anything else that can be seen, or felt, before the nose dive?

Is there any sure signs that will indicate a collapse?

Just curious...
