I forgot to include the following sentences. I really hope you can have a look at them, too.

1)Now the reality with which he is confronted fills him with horror and disgust.
2) He is disgusted and horrified by his creation- He rushes from the room and returns to his bedchamber.
3) He cannot sleep. At last, his tiredness wins over (?) his state of mental confusion. However, he is plagued by a terrifying dream.
4) He dreams about Elizabeth’s walking in Ingolstadt. He embraces her, but when he tries to kiss her, her lip become livid with the colour of death. At that very moment she turns into the corpse of his dead mother enveloped in a shroud.
5) He sees the graveworms crawling in the folds of the flannel (how can I rephrase this?). He awakens from his dream with a start.
6) His forehead is drenched in sweat and his teeth chatter. By the light of the moon, which forces its way through the window shutters, he sees the monster by the light of the moon.
7) The monster’s eyes were fixed on him. He opens his jaws and mutters some inarticulate sounds.
8) He stretches out one hand apparently to keep (detain?) Victor but he flees away out of fear and horror.

1) The protagonist of the story is now faced with a reality that fills him with both horror and disgust.

2) This reality is his own creation, and he is so repulsed by it that he quickly leaves the room and returns to his own bedroom.

3) Despite being exhausted, he finds it difficult to fall asleep. Eventually, his tiredness overpowers his mental confusion. However, he is then haunted by a terrifying dream.

4) In this dream, he envisions Elizabeth walking in Ingolstadt. He approaches her and embraces her, but when he tries to kiss her, her lips turn pale and lifeless. In a horrifying twist, she then transforms into the corpse of his deceased mother, wrapped in a burial shroud.

5) He observes the graveworms crawling in the folds of the flannel in his dream. When he suddenly wakes up, he is startled and filled with intense fear.

6) His forehead is soaked in sweat, and his teeth are chattering. The moonlight seeping through the closed window shutters allows him to see the monster standing nearby.

7) The protagonist notices that the monster's eyes are fixed on him. The monster opens its mouth and utters incomprehensible sounds.

8) The monster stretches out one hand, seemingly trying to hold onto or detain Victor. However, filled with both fear and horror, Victor quickly flees from the scene.

I hope these explanations help in understanding the sentences better.
