Michelle Gabrielli claims she has seen the strange lights two nights in a row at her home in Portland, Oregon, US.
Footage captured by Michelle shows a distant light which rapidly changes size and colour in the night sky.
Clearly stunned Michelle can be heard saying “wow, oh my God” repeatedly as the light constantly shifts above her.
Although the video only shows one light, Michelle claims there were at least 15 fluorescent orbs in the sky.
She shared her experience with KOIN 6 news in search of an explanation.
Speaking to the news site, she said: “I don’t know what that was last night. I can only speculate… it’s an unidentified flying object.”
Michelle also claims the lights would move apart and back together in the sky.
According to UFO expert Tom Bowden, Oregon state has the second most unexplained sightings in the US.
Although some believe the lights could be the work of a drone, others are convinced by Michelle’s UFO sighting.
One believer wrote: “This is real.”
Another commented: “Aliens jets are mysterious.”
But similar light formations have also been seen over Texas and California over the past few weeks, leading some to wonder whether extra-terrestrials have been visiting the planet.
Some believe Oregon could be home to more than just “aliens”, as footage has emerged of a potential Bigfoot spotting in the centre of the state.
The region has also seen its share of paranormal activity, with CCTV catching a tip jar moving by itself in a local marijuana dispensary store.
