But we tend to ascribe emotions, traits, and beliefs to these irreal objects as if they were real.
Throughout the book Sartre offers arguments against conceiving images as something inside a spatial consciousness.
Sartre says that what is required for the imaginary process to occur is an analogon—that is, an equivalent of perception.
This can be a painting, a photograph, a sketch, or even the mental image we conjure when we think of someone or something.
Ultimately, Sartre argues that because we can imagine, we are ontologically free.
In order to imagine, a consciousness must be able to posit an object as irreal—nonexistent, absent, somewhere else and it does so always from a particular point of view.
