If you live in a city that maintains sewer and water lines, there may have been some work going on in which the sewer lines were being suctioned and cleared of debris; if your Plumbing is in good working order and the building in which the toilet was located in was close enough to the suction, the toilet would 'flush' on its own. Another circumstance would involve dumping over a gallon of fluid into the bowl, causing emptying based on gravity alone.
There is about four to five gallons wasted if you flush a toilet but I don't believe that it makes a difference if the handle is loose or not. Unless, the toilet is leaking from the handle or somewhere else.
You usually depress a handle on the tank.
Linkage going to flapper is sticking or needs adjusted. Nut holding flush handle to tank may need tightened or replaced. Pressure assisted toilet needs more force on handle to flush.
Replacing a toilet flush handle is inexpensive and is generally a one person job. The handle can be replaced by opening the tank and unhooking the chain. Using a wrench you can now remove the handle. To replace the handle simply attach the chain and secure in place.

It could be that the chain attached the handle to the flapper is too long. that would be the easiest thing to try first.
A toilet bowl was made for people to go to the bathroom inside their house. To use a toilet bowl, you have to first sit on it and go to the bathroom. When you are done, you push the handle down to flush it.
