Ya it’s true because Everything is made of energy & vibrations.
That’s why everything has an Aura
The first Aura photo was made by the genius scientist Nicola Tesla in the 1890's
Yugoslav-American scientist Nikola Tesla took the first aura photo in 1891. By dangerously submerging himself in high voltage, Tesla was able to demonstrate the energy (aura) that surrounded his body.
