If you thought the story behind Matthew Coleman -- the QAnon-obsessed dad who confessed to killing his 2 kids because he believed they had "serpent DNA" -- couldn't get any weirder ... it just did.
According to new docs in the horrifying case ... Coleman told the FBI, last August, he'd been "seeing all the pieces being decoded like 'The Matrix,' and that he was Neo," before he says he murdered his children.
In that same interview, following his arrest, Coleman also talked to FBI agents about time travel, teleportation and claimed his kids -- 2-year-old Kaleo and 10-month-old Roxy -- had told him about babies being placed in fireworks, food and walls.
The affidavit, first obtained by People, is a truly bizarre read, and includes Coleman's assertion he had to kill Kaleo and Roxy because they might have been corrupted with serpent DNA from their mom ... and he had "to prevent them from becoming an alien species that would release carnage over the Earth."
Also interesting ... months before the kids were killed, Coleman spent hours each day looking up conspiracy theories online, according to one of his close friends.
His court date is set for May 19, and Coleman is being held in federal prison without bail.
