LF Harry/Voldemort Fic where Harry is saved from Ministry by Voldemort

[Guest TheReaderofHP]

Hello, I’m searching for a fanfic where Harry enters peoples dreams/minds and he meets up with Voldemort in the dream/mindscape so he can be rescued from the Ministry where is forced to be asleep and/or experimented on. He gives this same option to his half-brother or maybe actual brother as well.

Details remembered: He has a half-brother or actual brother and his father, James, is alive working at Hogwarts but Lily is not alive (I think). Harry joins Voldemort since he is the one who rescued him. There is some Wrong BWL aspects and a point in the story where the Light and Dark side meet up for a truce.

This is an old fanfic and I remember it being good so I would like to re-read after all this time.
