Bobby Brown sat down with ABC's Robin Roberts for an in-depth interview on 20/20 that left viewers scratching their heads.
The emotional singer claimed he had sex with a ghost in the mansion he and the late Whitney Houston purchased in the gated Country Club of the South subdivision north of Atlanta.
"I bought this mansion in Georgia. This was a really, really spooky place," he told Roberts. "One time, I woke up and, yeah, a ghost... I was being mounted by a ghost. I wasn't high. I was not trippin'."
Brown tearfully recalled the untimely death of his daughter Bobbi Kristina Brown, who passed away at a hospice in July after lingering in a coma for 6 months.
Bobbi Kristina was found face down and unresponsive in a bathtub at her home in Roswell, Georgia on January 31. She never regained consciousness.
Brown, 47, said Bobbi Kristina grew distant from him after the death of her mother, who drowned in a similar bathtub accident in 2012. He fought back tears as he recalled spending Father's Day with Bobbi.
"That was a special day," Brown remembers. He said Bobbi K made plans to move to Los Angeles 2 days before she drowned.
"If I could get those two days back, my daughter would be here," he said. "All I want is those two days back… I hate to say it but two days. If I had those two days back, I'd have went and got her instead of waiting for her to come to me, I'd have went and got her if I knew. She was to come out here to Los Angeles with me."
He broke down in tears as he explained Bobbi Kristina's final days, after he agreed to let her doctor give her Morphine to ease her transition to the afterlife.
"The hardest thing I had to do in my life was to tell my daughter to let go," he told Roberts. "My baby's gone," he cried. "I don't wish that on my worst enemy. That is the worst pain in the world."
Without naming names, Brown blamed Bobbi Kristina's boyfriend at the time, Nick Gordon, for both his daughter's and Houston's deaths.
"It's not a mystery to me," Brown said. "I know exactly what happened to my daughter. The same thing that happened to my daughter is what happened to Whitney. There's only one person that was around both occasions, only one person who says they were there to protect them and he didn't."
He added: "He knows what happened. I don't know what happened that night, but he does."
