We went on to   a walk through the strang   strange city looking for the green bus. I couldn't believe that we did it. that. It looked like someone's jokeIt seemed like a joke. The sky was dark, there wasn't  it was like there wasn't a Moon in it  moon in the sky. There was (were? was is correct but many is not the right adjective) many much trash liying on the ground of roads. We didn't notice any cars, whatever (or anyway? anyway would work, but whatever is strange because when it is used that way it is negative in meaning) we went across the street to the sidewalk. When we passed the  a crossroad  and we continued to go ahead forward. A few minutes later , we spotted a gas station in front of us. An old man met us when we approach. there.
"Good night evening strangers!Can I think  you must be going very far tonightare going from far away...?" he said.( greeting at night time is: Good Evening, good night is only used when you are going to sleep.)
"Good night! evening!Yes, you're right. We are in a hurry." I said.
"You have nowhere to hurry to. Throw away out my the garbage!"
Do it yourself! I answered.
"The garbage is in your head!"
"What?"
"You still haven't noticed the girl next to you is absent not there."
"What?" I repeated.
"Yes, this man is right. I'm just your illusion, your dream." Lisa said.
"Then why are you here? Why have you followed me all this time?"
"I came to these strang strangeworlds to save you" Lisa answered...

I hope this is not disgustingly :)

Do you mean: I am in a airport security line delay? If that is what you mean, I would think, that you are being delayed because you need to have your information checked at the airport.

Extrange history

One day I was walking around the mountain and sudlenly I heard one noise I could look a lot off people dancing and singing.

It was a good suprisse to me. I ate with them and after in fact every body to return again in her particular car. The car flew. I was suprised and alone again.

At the moment I decided to return to civilisation with my family and friends.

A Strange Event (I would suggest this title because it would introduce what you are talking about- something that happened to you- an event, or even you could say experience- most people will not call a past experience a history in English)

One day,  I was walking around a mountain.(this means not on the mountain but on the ground around it/ if you mean walking about on the mountain- then you can say" I walk walking on a mountain aimlessly/ or walking around on a mountain)   All of a sudden I heard a noise, this made me look around, and I saw a lot of people dancing and singing.

This was a pleasant surprise for me.  I ate with them.  After, everyone return to their car.  The cars quickly drove away.  This made me surprised, and again alone. At that moment,  I decided to return to the city/ civilization to be with my family and friends.
