Well, without more context, it's difficult to give a detailed account of 'the people next door true story'. It could potentially be a horror - type story where the neighbors are involved in something sinister. Or perhaps it's a documentary - style story that uncovers the secrets and daily lives of the people living next door. It might also be a comical take on the typical neighborly relationships, full of funny misunderstandings and anecdotes.
Definitely not a true story. 'The Shrink Next Door' is made up for entertainment purposes. It doesn't draw from any real-life situations or individuals.
