In old school parlance, the idea of RRTEI applies here, Roll Randomly Then Explain it. This means that you accept the result of a random roll, and now you have to explain it in the context of the game world/environment/adventure https://twitter.com/yum_dm/status/1288721447897071617

So you never just roll "a dragon" and then attack. You roll "a dragon" and say, why is it in the area, what is it doing, how would it react to the party, that sort of thing. The classic example for me was the time that the party rolled a blue dragon as a wandering monster

They were near a hidden shrine, and the players were stuck looking (but not yet finding) the entrance. I rolled for random encounters as they had been at it for a few hours. The dragon landed and started lunching on their camels. There was parley. I rolled for encounter reaction

And it came up "enthusiastically positive". Right there and then I had to figure out WHY this dragon, who was able to slay the party with one or two hits of his breath weapon, would react "enthusiastically positive" to this party. I decided the dragon wanted into the shrine

And he told them he was too big to use the entrance, he wanted the party to go in and deal with whatever was inside, he would take them out on departure. So he offered to show them where the shrine was, and blast open the doors, if they would agree to give him "all the gold"

I find many refs discard results from random rolls when they don't like them. And that's OK, there can be times when you don't realize you want a particular result UNTIL you roll the dice. That's cool.

But forcing yourself to make a random result MAKE SENSE, is one of the most effective worldbuilding and improvisation tools there is. And that encounter with the dragon was ROLE PLAYING GOLD, so much fun, and the players loved it.

I always put a few "not obviously combat" encounters on these tables, wandering minstrels, caravans, pilgrims, etc., this, and giving you monsters interesting motivations and reasons for being where they are can create avenues for adventure.
