Well it doesn't necessarily mean what you get at search results. I am very aware about my dreams and I can get you a few tips

Be careful about what you Google about in dreams. They mean different things for every person because every soul is a bit different.
Look for feelings in your dreams. What did you feel when your teeth dropped out? our unconsciousness wants to communicate with things like this to our concoiusness. You need to interpret every stupid thing to analyze what your inner fears/desires are. 
Nightmares about dreams falling out often came from fear that a big change will come that will change everything you know is normal. I don't 3ant to loose my teeth because I need them and they are precious. I had those dreams when I stood very barely in life and my future wasn't sure. If you want to analyze your dreams more, which I recommend to understand yourself better, try to write them down as fast as possible after waking up. Everytime you do that, your brain will have it easier to remember those dreams

Tonight I had a dream where I took a plane back home and when I walked into my room there was cocaine everywhere. I then snorted some of it on my desk. What does that mean?

Lmao i can't tell you what that means but i've been having cocaine dreams frequently as well. I just interpret it as a desire to do coke, the dream being a warning that i am predisposed to become an addict, so i just have to be careful. I've had similar dreams before i started smoking weed, i stopped now but i still dream about it. Oddly enough i never dream about alcohol even though i drink every day.

I sometimes dream of collecting crumbs of coke or weed all over the place in order to have a last hit
