Re: clogged main drain line
I suggest you contact a plumber that can *scope* your main waste line from the inside of the home to the street. The *scope* is a camera the plumber snakes down the line to allow them to see if it's simply a blockage or if there is an actual problem with the line. This way you can see the condition of the main line --- signs of broken , collapsed , shifted lines , open connections allowing tree roots or you may simply just have a blockage.

If that lower toilet tank constantly empties then you have two issues. In which case the toilet constantly running may require replacing the flapper or adjusting the flapper mechanism ( chain or rod ).
I suspect if you woke up to find water on the floor and a low level in the bowl ---- that's likely from a blockage. Once you flushed the toilet and there is a blockage --- preventing the bowl to empty --- while at the same time the tank is filling the bowl ---- the bowl overflowed spilling over onto the floor.
The blockage is probably enough to allow a trickle of water through but large enough to block a large amount of liquid being discharged rapidly --- like the toilet or the washing machine.
Over the course of time ( say overnight ) the water from the toilet eventually drained --- lowering the water level in the bowl.
