Orbs are considered to be spirits or supernatural beings that travel in the form of balls of light. Orbs are also known as "ghost orbs" or "spirit orbs" and are often thought to be the souls of people.
They may not always be spherical in shape, but oblong and hazy on film and may or may not have a trail attached.
Although rare, they can be seen with the naked eye and can be caught on camera. Videos of orbs are quite common, showing light anomalies moving across the frame, either floating or traveling at a high rate of speed.
“If quantum mechanics hasn’t profoundly shocked you, you haven’t understood it yet. Everything we call real is made of things that cannot be regarded as real.” – Niels Bohr
