Como apontado pelo OP em um comentário , isto é Slayers (2011) por CJ Hill, o primeiro livro da série Slayers .
Em Goodreads :
Dragons exist. They're ferocious. And they're smart: Before they were killed off by slayer-knights, they rendered a select group of eggs dormant, so their offspring would survive. Only a handful of people know about this, let alone believe it – these "Slayers" are descended from the original knights, and are now a diverse group of teens that includes Tori, a smart but spoiled senator's daughter who didn't sign up to save the world.
The dragon eggs have fallen into the wrong hands. The Slayers must work together to stop the eggs from hatching. They will fight; they will fall in love. But will they survive?
Mais precisamente ...
Essa pessoa estava tendo um sonho muito vívido sobre um dragão aterrorizante que tentava alcançar a pessoa no sonho.
Mrs. Harriet Davis had never been afraid of dragons— until now. The dragon in her dream hovered above Washington, D.C., watching traffic. Against the fading light of the evening, its body seemed first brown, then maroon, then the color of blood. The dragon turned its head side to side, presenting a face that looked like a cross between a crocodile and a cat, although with more disdain than a cat and less patience than a crocodile.
No final do sonho, o dragão consegue pegar essa pessoa ou simplesmente arranha-a.
Depois que o dragão se aproxima de Harriet e respira fogo, os cidadãos com quem ela se agrupou acham que ele se foi, mas é quando o dragão tenta dar um golpe final.
“Is it gone?” a man beside her asked. Before she could answer, a searing hot claw grabbed her shoulder from behind.
É nesse momento que a pessoa acorda e encontra arranhões em si mesma.
A cena a seguir confirma isso e a parte "pode ter sido uma menina e eu tenho certeza que ela estava grávida":
Harriet gasped, let out a strangled scream, and found herself sitting up in bed.
Allen threw off his covers and turned on the lamp on their night-stand. His blue eyes
were wide, but not quite awake as he jolted out of the bed. “What is it? Is the baby coming?”She shook her head and drew her knees up, trembling, gasping. “A dragon grabbed me! Its claws burned into my back!”
Allen stared at her a moment, then laid back down with a thump and shut his eyes. “Okay, let me know when it’s the baby.”
[...]
“My shoulder burns like crazy.” She slid her nightgown away from her skin and gasped. Three long welts ran across her shoulder and down her back. “Look!” she cried. It was proof she would rather have not found. A wave of nausea swept over her.
Allen sat up, squinting at the welts. “How did you get those?”
Her voice spiraled upward. “I told you. It grabbed me.”
Esta pessoa e o marido (?) ligam para alguém com a experiência certa para ajudá-los.
Quando ela estava sonhando, Harriet se lembrou de um cientista no rádio, falando sobre como os dragões eram reais. Não ouvira o que se seguiu, pensando que não era sério, mas depois do sonho que teve, ela e o marido procuraram o dr. Alastair Bartholomew, que passara a vida estudando dragões. Ele fala sobre como seu filho será uma das novas gerações de Slayers, e é por isso que o dragão tentou matá-lo no útero.
