An eerie clip has emerged of people being knocked over by a mysterious energy wave while at Lana Del Rey concert.
Filmed in Mexico City, the video shows fans hurtling towards the ground as the singer performs in the background.
After being uploaded to social media, fans have been speculating over the spooky clip. However, there is a surprisingly simple explanation. Take a look for yourself:
It happened as the Grammy award winner took to the stage in Mexico City, with the concertgoers eager to see the singer perform at the Foro Sol.
As they film and wave along to the music, the unexpecting audience are suddenly hit by a mysterious pulse of energy.

Toppling into one another, Del Rey’s fans hurtle to the ground in a mass domino effect as they enjoy her Did You Know That There’s a Tunnel Under Ocean Blvd tour.
Eerily, you can hear people screaming as they hit the ground, with the person filming also falling as they too are hit by the energy wave.
It’s unclear how many people were injured in the August 17 incident, but the strange moment has seemingly captured everyone’s attention.

Fans are now speculating about what happened at the concert, as the clip was uploaded to Lana Del Rey fan page and has since gone semi-viral on Twitter.
Unsurprisingly, the comments are littered with conspiracy theories - in fact, one horrified fan said that they’d never experienced anything like this at a concert.
They tweeted: "I've been to many shows. NEVER saw anything like this," whilst another reacted to the strange incident, insisting: “People don’t fall like that.”
Meanwhile, a third had a particularly strange explanation for the incident, writing: “Evil spirits and demonic energy exists.”

Well, you can put your tin foil hat away as one crowd science expert has revealed just what happened at the Mexico City concert.
Speaking to The Messenger, G Keith Still explained that the weird effect was due to ‘progressive crowd collapse’, adding that it is ‘where the momentum of one person knocking into another increases significantly’.
The bizarre effect can happened at events where crowd flow hasn’t been regulated, which can result in the ‘domino effect’.

He told the press: "If you stack dominoes up, a domino can knock over another domino one-and-a-half times its size, simply because you're turning a potential energy into kinetic energy. You're changing the force.”
“So it's very easy when you get into close proximity when the crowd is packed together to actually knock the whole thing over as one."
While thankfully no one was seriously injured on August 17, the dangers of progressive crowd collapse are very real and can be fatal.
The expert warned that there are high risks of asphyxiation, with most people losing consciousness after 30 seconds and being declared brain dead after six mins.

Even more eerily, this latest case happened nearly two years after the Astroworld disaster, which claimed the lives of ten people.
