The whole room is filled with spheres of violet light.
Imagine you see violet light.
SEE THE VIOLET LIGHT.
Envision a sphere of violet light and enter it.
I'm entering one of the spheres with my mind. I feel that they're carrying the message: "We are here. We love you infinitely, eternally and unchangeably. May the Force be with you." The room becomes Real. The three-dimensional space of the room loses its interest when the violet spheres appear, which monopolise my concentration.
