When I returned to the dorm room, I felt physically and mentally exhausted – mostly due to psychological depression and panic, as well as guilt. When I came out of Wu Haoxuan's house, his parents thanked me so much and gave me some gifts. But I realized that I hadn't been able to really help their son much. I only now realize that Wu Haoxuan was right about what he said to me at the beginning - I couldn't help him at all.

Well, I don't want to think about it anymore. In order to adjust my emotions, I think that the same things I suggested Wu Haoxuan did would also apply to myself. After taking a shower in the bathroom, I turned on my computer, watched an American humorous spoof movie, and forced myself to giggle for more than an hour — but anyway, I was in a much better mood. At 11 o'clock, I went to bed.

Lying on the bed, I still can't help but wonder - will Wu Haoxuan have that nightmare again tonight? The answer will only be known tomorrow.

I was wrong, and the answer came out sooner than I expected.

In the middle of the night, I was sleeping soundly when I was suddenly woken up by the ringing of my phone. I picked up the phone in a daze, and when I heard the first words of the other person, the drowsiness disappeared immediately.

It was Wu Haoxuan, his voice was mixed with infinite horror and fear, almost with a crying voice: "Teacher Yu, I just ...... I woke up from the nightmare again, and sure enough, it was 4:17 again......"

I glanced at the time on my phone, it was 4:20 in the morning, and it seemed that Wu Haoxuan was calling me immediately after waking up.

The trembling and crying voice on the phone continued: "Teacher Yu, that nightmare...... It's terrifying...... I still can't control my shaking. But...... I just can't remember what the dream is. But I knew something was going to happen...... It's tomorrow night...... Teacher Yu, I'm really scared, what should I do......"

Wu Haoxuan's desperate voice made my heart sink gradually, and I became helpless. But in the face of this strange thing, I really don't know what to say. I want to comfort him, but I'm afraid my own voice sounds even more flustered: "Don't panic, Wu Haoxuan, you...... Let me think, okay, let me think. So, tomorrow morning, I'll call you, and we'll talk slowly. Don't worry, don't cry...... I thought, everything will be fine......"

I just whispered incoherently to him some insignificant words of consolation, which at least calmed him down a little. After the call, I lost sleep, and I lay in bed tossing and turning, thinking about it, trying to connect the strange series of events in a logical way and arrive at an explanation. But I thought about it all night in bed with my eyes open, and I didn't have the slightest clue. I just felt that the more I thought about it, the more terrifying it became, even though I was wrapped in a thick quilt, it also made my body chill and shudder.

By morning, I still couldn't think of any plausible explanation, let alone a solution. This made me embarrassed - I promised to call Wu Haoxuan in the morning, but what should I tell him when the phone called? If I told him that I couldn't give him a clear solution and coping with it, wouldn't that make him feel even more hopeless and helpless? Moreover, I also had a faint feeling of uneasiness - maybe this matter is beyond the scope of our normal cognition, and I should not get too involved, otherwise it may lead to trouble. Due to various considerations, I didn't call Wu Haoxuan for the whole day, and unexpectedly, he didn't call me either. I don't know what state he is in now, but I am optimistic that maybe he has learned how to adjust himself, and silently pray in my heart that he will be safe.

And so I spent Sunday in trepidation.
