Небольшой диалог о хороших или плохих снах.

- Hello, John!  Why do you look so tired?
- I had a bad dream last night.  In my dream I was falling off the rock.  So I am still thinking about it
- Oh my god!  I am lucky.  I never remember my dreams.  I only sleep longer if the dream is pleasant and wake up earlier if the dream is a nightmare.
- You are really lucky.  Because I remember almost all my dreams.  For example, last week I saw a dream in which I was travelling to other planets.  That was wonderful. 
- That's a nice dream.
- Yes, and the next I had to go to the country to see my old aunt.
- Really? And what are your plans for tomorrow?
- I have no plans.  But I am taking my Chemistry exam tomorrow.  I hope my dream has nothing to do with the exam.  Though I don't know Chemistry very well.
- OK.  Let's hope for the best!
