They are really quite rare dreams. In my case, the only recurring dream I've had in my life has been to arrive at the time of my graduation from college and be informed that I didn't pass a subject, so I had to repeat everything I had already seen! Thanks to that, at the end of each year, I would ask for certified grades, to prevent it from happening.
However, when I applied for the degree, they told me that my thesis grade was not registered in the system, so I ran home to get a copy of the verdict so that they could write it down and give me the approval.

Realmente son sueños bastante raros. En mi caso, el único sueño recurrente que he tenido en mi vida, ha sido llegar al momento de mi graduación en la universidad, y ser informada que no aprobé una materia, por lo que tenía que repetir todo lo ya visto! Gracias a eso, al finalizar cada año, pedía unas notas certificadas, para evitar que se cumpliera.
Sin embargo, al momento de solicitar el grado, me dicen que la nota de mi tesis no estaba asentada en el sistema, así que corrí a casa a buscar la copia del veredicto para que lo escribieran y me dieran la aprobación.
