Your grammar could do with a little improving in a couple of areas. The problems lie mainly with sentence structure and/or sentence length as opposed to word use.
"Tonight at midnight I woke up by the breath of a dinosaur which was standing just beside my bed and breathing in my face. If its breath had not been the smell of rotting tomatoes this wouldn't have been so bad."
A couple of errors here. I'd revise to something along the lines of:
"Tonight, at midnight, I was woken up by the breath of a dinosaur which was standing just beside my bed and breathing right in my face. This wouldn't have been so bad if its breath didn't smell of rotten tomatoes."
There are similar problems throughout - you tend to write very long sentences without much use of punctuation. This results in ridiculously long areas of text that are difficult to read. Another potential revision might be:
"When I had decided it was time for some coffee and the green haired man behind the desk said that it was going to cost me 3 rocks and five nasal hairs and gave me a chainsaw."
"When I had decided it was time for some coffee, the green-haired man behind the desk said that it was going to cost me three rocks and five nasal hairs. He then gave me a chainsaw."
etc.
Considering the fact that this was originally written in Swedish, most of the points I've made are redundant, and I couldn't offer you any help on that if I tried.
Glad to see that someone's got some original ideas, though. This is the sort of stuff I always wished I could put down into writing. Mind you, I haven't tried in years...
