СРОЧНО!!!!!перевести диалог в монологKatie: Good morning, Lizzie.
Lizzie: Is it?
Katie: I think someone got out of the wrong side of the bed this morning! What's the matter?
Lizzie: Oh, I'm just a bit tired, that's all. I had a horrible nightmare last night. I woke up shaking like a leaf and with my heart pounding. Then I couldn't get back to sleep.
Katie: Poor you! What was the nightmare about?
Lizzie: Well, I was trying to get to an exam, but my legs just wouldn't move.
Katie: So... did you finally get there?
Lizzie: Yes, but then I realised that I couldn't answer any of the questions!
Katie: Oh, that's terrible! I once dreamt that, either. I looked it up. It could mean that you are afraid of letting someone down.
Lizzie: That's a thought! So it doesn't mean I'm going to fail my exams then?
Katie: No, don't worry. Nightmares are just your subconscious mind trying to deal with all your stresses and worries, that's all.
Lizzie: That's a relief!
