Eidetic Hazard

A memory becomes an info-hazard.

You only got a glimpse of the eldritch horror before it vanished into the ether but your eidetic (AKA Photographic) memory keeps every detail of the abomination etched into vivid existence across your thought patterns. Your memory has always been a useful asset but with every passing moment the line between memory and reality blurs.

It's already too late.
Every time you remember, it sees you.
