If water is trickling in the toilet for hours, then for some reason the valve in the cistern is not cutting off the supply, and if the cistern is fed by a tank in the loft, that could explain the sound of water running/ dripping up there.
If water is running into toilet it must be running out somewhere, i.e. through an overflow pipe, or out through the main pan waste pipe.
Checking the route of any overflow should rule out any connection with wet carpet.
If possible, lift the carpet and check underneath for water coming from below.
Could the wet patch be the result of something having been brought in covered in snow, or from melted ice?
