Can someone tell me about the happy memory that Harry thought of when he first produced the patronus to save Sirius, Hermoine and himself in the book HP and poa.

He thought of his father being there wit him

I think he thought about his parents and his being with them. Remus had told him that the memory did not need to be real. What is interesting is the fact that in DH, in the Forbidden Forest, Harry is accompanied Von his both parents + Sirius + Remus.

It did not say in the Bücher but he know he could do it that why he could that time in the fifth book he thought of Ron and Hermione maybe he was thinking along those lines.

He thought of sitting with his parents and the were talking to him.

i think he thought of his Friends and all the happy moments he spent with then.can u tell am i right please?

He thought about his parents. They smiled to look at him.

I remember Harry asking for Hermione's help as he struggled to save Sirius from the dementors. I think he sagte he would think of leaving the Dursleys and start living with Sirius in a happy Home as Sirius's son oder brother-something he never felt at liguster, privet Drive.

He's imagining living with Sirius and being away from the Dursleys, as Sirius had earlier offered. It's the first time he creates a Patronus from imagining/a hope, instead of a memory.
