You have wished you would notice, but it seems there is someone watching you. From afar, from the distance. You were suspicious of this black smoke that suddenly disappears when you go closer to it. It was unnerving, could you possibly have a stalker?
At night, you will always have the same uneasy feeling. It's so foggy and rainy, you can't see. It's all dark, you just wish it was daytime. But then, something moves from the distance. Even if you couldn't see clearly, you can tell that something moved. Or someone.
It made no noise, and this piqued your interest. You slowly took a step, then another. You went to literally where that noise was, but you can't see anything. Then, you felt the uneasy feeling again from behind. It seems someone is clearly watching you, and when you turn from behind you see a tall figure with white eyes and a smile who quickly runs away when you spot it.
And you could have sworn you saw it looking at you while going back to running.
