In psychology:

How many windows are on the front of your house?
Intuitively this feels like a picture in the head
Theoretically, if the person gets this right then there must be some sort of stored representation of the house. (Otherwise they would have to have already counted the windows and stored this info as a semantic fact.)
Our ability to form mental images is:
Spontaneous - Don’t think of an elephant
Effortless - E.g. It occurs during sleep
Extremely Useful - Problem solving & mental practice
Hypnagogic dreaming often occurs during the semi- conscious descent into sleep.
It is an image-rich experience
There have been some famous outcomes from hypnagogic dreaming...

Founder of modern mathematics
