past Harry time travel

Harry's fourth year he get's sent 100 years in the past during Dumbledore 14th birthday and the only way forward is for harry to turn sixteen and carry the next headmaster child. there's a lot interaction with different students Albus doesn't remember past Harry until a major event, Harry's child in born by magic gene spell there's nothing phychiacal going happen between Albus and Harry. This story has weird pairing well i find weird i put Gryffindor's and Slytherin students as a couple. I like blending houses together This story happened because of weird dream
