Most memories are far from coherent. In order, or even fragmentary visual recall is probably what we think of most intuitively as ‘memories’ but those are not the most common. Memories are often out of order or without context. Memories can be an image, or a sense of touch or heat or cold. They can be a memory of a smell, or a sound, or a taste. They can be merely the memory of an intense emotion.
We are just as likely to remember the touch of someone’s hand, or the smell of their aftershave as we are to remember their face, or the day we met them.
