Knowing

A spider.
Crawling.
On the white wall.

Then you open your eyes and realise it was a dream. You have fallen asleep. Unintentionally. You were scared. You were actually scared for your life. You woke up and it was all a dream. A nightmare. But why it does not feel so? It is over, you thought. Then why does it still feel this way?
Wide awake.
You look behind and check the wall. Twice. No sign from it. How can it be possible? Seconds ago it was there. You were certain. You knew. It felt so real. It feels.
Now?
You close your eyes and then you open them again. You can't remember the dream, can you? All you can recall is the spider. Crawling. You saw it, did not you? You felt it.
You did not feel the spider, did you? It was not it that you feared. It was not the reason. You know. You cannot lie.
Breathe.
You are awake now. Yet you still feel threatened. You don't need to ask why, do you? Cause you know. You always, always know. But knowing does not help, does it? It does not change a thing. Yes, you wish it did. Don't ask yourself the same question. Stop it. It is not over. It will not be over anytime soon. It cannot be.

It was not just a dream, was it?
