Old video of people using radio frequencies and a foil sheet to communicate with interdimensional beings?

I remember this video from like 10-15 years ago, it must’ve been on YouTube The video was of these guys, they had what looked like a large tin foil sheet that they had hung up in the frame of a door or something – making a sort of veil? They were using radio frequencies against this foil and it would generate these.. figures? In the foil? I remember them discussing about the beings from another dimension and how they can present themselves, or something like that

It’s hard to remember all the details, but with all these UAP hearings and the focus of interdimensional instead of extra terrestrial reminded me of this video, anybody else remember this video?
