There's likely a hidden point system at play. Every action probably doesn't contribute to it equally, for instance I think drinking the potion Omeluun makes for you gives more points than probing someone's mind during dialogue. There's also a priority scenes play in, you won't get more than one every night, some seem to be overridden entirely, I think Tadpole dreams are low priority, something like Raphael I think overrides everything else.
