Reference Request: Where can this story about nightmares be found?

I hope this finds you well and happy. I’m pretty sure I read it in the Pali Nikayas. It is probably one of the texts used as the basis of the idea of a ‘merit bank’ which I have found amongst ethnic Buddhists **especially**. It is the story of a person (prince/king?) who goes to the Buddha with a report of a repeated (?) nightmare, of people (monsters/ghosts/demons?) moaning and begging for food at his residence. The Buddha advises him that it’s because he didn’t share his own meritorious actions (puñña) with relatives (bandhu?) in the past. So, he should do so in the future to avoid this. best wishes Joe
