How to write a haiku poem?

Without any introductions ^^

1. Haiku is a kind of Japanese poetry. It consists of three lines: 1st line - 5 syllables, 2nd line - 7 syllables, 3rd line - 5 syllables.
2. After signing the alliance between Japan and Nazi Germany, the number of syllables ​​can be arbitrary for European languages but the proportions must be observed. 3rd line should always be a little bit more than others.
3. Haiku consist mostly of metaphors as well as there is no need to present personal pronouns. Also, it is advisable to avoid commas.
4. Typically, the subject of haiku are some personal experiences, mood and what is happening around you. However, all this must be veiled metaphors and be impersonal.
5. The first two lines should relate the plot of haiku and the last - bit abstract and unexpected final.

An example of a haiku:

Warm and nice place
Light can be nothing or something
Predator awakes

Explanation: I'm sitting in a room at the computer. Monitor lights and I can do something useful or do nothing through it. I hear that the cat awakes and meows. The ratio of 5-8-5, no personal pronouns, the plot is not obvious, the ending is a little abstract and can mean anything :)
