When the classroom door opened everybody went silent.
I was sleepy because the lesson was really boring and I almost didn't sleep last night because I was studying for a test but when I saw a very strong light from the door i waked up.
Everybody was very confused. Teacher said that she will go check what is it. After 5 minutes we heard a scream everyone was really scared. Teacher came back and she said that she had never seen anything like that before.
Then we saw that things. It was a couple of small grey-green creatures witch big eyes, small noses and mouths, long fingers and they were very ugly.
Everybody was panic. I took a deep breatch and i ask one of them: "who are you and what you want from us".
It looked at me and say something but i didn't understand they language. Nobody try to escape becausewe were really afraid of them. Suddenly I saw another strong light from the door. It was so strong that i didn't see antyhing in our classroom. I didn't remember anything more. When i waked up the creatures disappear and everybody was learning. Nobody remember anything. They say that i am crazy or it was only dream. But i know something
happend that day...

I was studying for a test, but when I saw a very strong light from the door 'i' (I-duza litera) 'waked' WOKE up.
THE teacher said that she will go check what 'is it' IT IS. After 5 minutes we heard a scream - everyone was really scared.
THE teacher came back and she said that she had never seen anything like
that before.
Then we saw 'that' THOSE things. It was a couple of small grey-green creatures
'witch' WITH (witch-to czarownica) big eyes, small noses and mouths, long fingers and they were very ugly.
Everybody 'was' (niepotr) panicKED. I took a deep 'breatch' BREATH and I askED one of them: "who are you and what you want from us".
It looked at me and 'say' SAID something but 'i' (postaraj sie o to I) didn't understand 'they' THEIR language. Nobody 'try' TRIED to escape because we were really afraid of them.
When I 'waked' WOKE up the creatures disappearED and everybody
was learning. Nobody rememberS anything. They say that 'i'I am crazy or THAT it
was only A dream. But 'i' I know something happenEd that day...
