What makes an image stick in a memory palace?

Make it vivid, exaggerated, absurd, moving, and multisensory — the brain remembers the strange and the striking, not the ordinary.

The levers, all pushing the same way (toward unforgettable):

• Exaggeration — giant, tiny, hundreds of them, absurd proportions.
• Motion & action — things happening, not static objects.
• Absurdity / humour — the bizarre survives; the mundane fades.
• Multisensory — add sound, smell, texture, not just a picture.
• Emotion — funny, gross, shocking, or personal images cut deeper.

A calm, realistic image is a forgettable image. Crank every dial.
