You and Holmes were walking through the forest looking for some Hound - a large wolf that was supposedly created in a laboratory near this small village. (Sherlock already knew that no Hound existed, he was trying to understand what was causing such hallucinations...

A drug? He should think about it while they were walking through the forest) You didn't believe in all this and walked without any fear until suddenly a fog (Fog is a drug that making people hallucinate) appeared and you heard a growl?..

You noticed something huge... strange, similar to a wolf, the eyes of this creature were glowing red

You began to panic and retreat until you fell to the ground

Sherlock looked at you with poker face.
