Nightmare Incarnate

Weak: Disturbing sounds- Are those footsteps? A demented laughter somewhere in the distance? A person's dying screams? Is that a whisper you can hear, carried in the wind? This place is really freaky...
(Causes paranoia or similar effects, depending on your character. Strong-willed characters or people with a great ability to maintain their calmness can resist this to a great extent, though not completely. Having multiple weak enemy dices means that these sounds "stack", and so their effect becomes greater and perhaps even capable of breaking even the toughest of people. Duration is 3 posts.)

Normal: Poltergeists- Trees falling down, rocks suddenly shooting towards you, having your body strongly pushed away without any explanation. These anomalies can deal some serious damage or scare the living daylights out of you. They might even separate you from your allies. Be on guard. (Single poltergeist per normal monster encounter.)

Strong: The unknown figure- You can feel it, can't you? Just beyond the mist, it's hollow eyes staring right into your soul, sending ice-cold chills down your spine. No matter where you look it's there. Always watching, always moving. And no matter what you do, it's always just beyond the mist.
(Greatly frightens you, triggering your fight or flight mechanism. Whether you choose to attack or run away and hide depends on your character's personality. If this occurs in the early stages of the mission, before you've encountered the other anomalies much it will not have that great an effect. Encountering this in the later stages, however, will trigger your fight or flight mechanism, guaranteed.
Duration is 4 posts, extended depending on number of strong monster encounter dices rolled.)

Boss:Fear impersonated- Your time is up. The chase is over and now you must die. And it is coming to do just that. The unknown figure that had been stalking you until then finally appears before you, for better or worse. It's a humanoid about 2,5 metres tall, clad in black, but that's all you can make out of the figure.
It's attacks are unnaturally fast, it's reach long and it seems that it can attack you with it's tentacles, cutting you with them and letting you bleed. (This is a B-rank monster. Also please note that defeating it means that it does not die. Instead it escapes back into the mist, which gets raised soon after, and leaves behind several torn pages).
