A phantasma is essentially the same as a 'phantasm': an illusion, a deceptive appearance, or a figment of the imagination. Think of it as something unreal that seems real, a trick played by your senses or mind. Like a ghost or a vivid dream, it lacks physical substance. It can be a product of your imagination, a fever dream, or even a hallucination induced by something. It's fleeting and insubstantial, like smoke and mirrors.
