"Muahaha!"

You look over your shoulder -- not sure where the haunting giggle came from.

"Sure, I can laugh. Tee-hee!"

It's dark. No one else is home. Then, you realize:

Alexa is laughing on her own.

Amazon is working on a fix after users reported Alexa-enabled devices giggling out of nowhere or after being asked to do something else, CNBC reported .

"We're aware of this and working to fix it," Amazon said in a statement, CNN reported. In a later statement, Amazon said the device can mistakenly hear the command, "Alexa, laugh."

"We are changing that phrase to be 'Alexa, can you laugh?' which is less likely to have false positives, and we are disabling the short utterance 'Alexa, laugh.'" Amazon said. "We are also changing Alexa's response from simply laughter to 'Sure, I can laugh' followed by laughter."

Users who have been freaked out by Alexa laughing at them or defying them have shared their experiences on social media.

Laughs ranged from an evil "muahaha!" to a friendlier "hahaha!"

Some users weren't sure if they'd ever sleep again after hearing a childlike "tee-hee."

After hearing about the issue, others asked Alexa to laugh.
