"I finally started dozing off because I was so tired. I woke up and thought that my cat had touched my arm but realized it wasn't cat fur a few minutes later," Humphries told WTVF-TV. "I reached up and looked even farther, and when I raised my head up without moving my arm, whatever was in the bed raised up also and it was a small head."
Humphries said she grabbed a flashlight and revealed the identity of the intruder -- a 3-foot-long snake.
"I yelled for my daughter downstairs. I was in shock because I've never had a snake in my house. I've never even had a mouse in my house," Humphries said.
Cheatham County sheriff's deputies responded to the home and removed the snake, identified as a non-venomous rat snake. It was relocated to the nearby woods and released.
Humphries said she believes the snake got into her home through a basement flood drain.
"It gives me chills down my spine when I think about having a snake on my bed that was actually laying on me," Humphries said.
She said she isn't the only one who was a little freaked out by the situation.
"I even tried to get folks to come over and watch a scary movie in the dark the next night. Nobody [was] game for that," she wrote on Facebook.
