TERRIBLE: Man Beats Up Girlfriend All Day Long Because She Cheated On Him In His DREAM (PICTURED)

A Florida man spent an entire day beating up his girlfriend after dreaming that she cheated on him, police said.

Carlos Gascon allegedly punched and slashed his lover with a knife before slamming her down on a glass table — after waking up convinced she’d been unfaithful.

The 27-year-old also smacked her dog, threw it to the ground and then tried to choke it with his foot at her Summerland Key home on Friday. He’s also accused of pouring scalding hot coffee over her body, threatening to kill her and throwing her cell phone and keys into a nearby canal.

The victim suffered the vicious assault from early morning until 6:45 p.m., when Gascon finally passed out — and she was able to dial 911 from his phone.

“She said he was angry at her because he had a dream she was cheating on him,” Becky Herrin, Monroe County Sheriff’s Office spokeswoman, told the Miami Herald.

Gascon, from North Miami-Dade, was arrested and faces a slew of charges — from aggravated assault and battery to false imprisonment and animal cruelty. He is currently being held on $265,000 bail at the Monroe County Jail.
