It's not uncommon to see a possum on the side of the road, but it's where one San Antonio woman says she found one that will make you think twice before getting in bed.

Nicole Johnson has an apartment at Sierra Ridge Apartments on Patricia Drive. She doesn't plan to go back, though.

Johnson was sleeping in her apartment when, all of a sudden, she felt something strange.

"I feel something on my back, and I'm just like, 'What's on my back?" I'm thinking maybe it's my comforter or a sock? I don't know," she said.

It was neither of those things.

"When I realized what was in my hand, I just flung it against the wall," said Johnson.

Johnson had a baby possum in her bed.

"I'm still trying to figure out if I'm dreaming then I notice my finger is burning. I look at my finger, and I'm bleeding. I have a small scratch and then a puncture on the other side of it," said Johnson.

Pest control came and eventually found the animal hiding behind a dishwasher, near a hole where it's believed to have made entry.

"Babies are usually just trying to take care of themselves. They could have been hungry. They could have been looking for a nice place to rest," said Kat Wheaton, who works with possums at the San Antonio Zoo.

Experts at the San Antonio Zoo said possums help fight Lyme Disease by eating ticks.

Babies don't usually go far from their mothers, as Nicole found out. It's believed the possum's mom died in the wall.

Nicole went through a series of painful shots to make sure she didn't catch any diseases.

She's now asking to be released from her lease at her apartment complex.

A spokesperson for the apartment complex issued an apology and said it is working with Johnson to come up with a solution.
