similar dreams.

the past couple days i've been having obvious dream signs which i have not picked up on :(

-i had a dream where i missed my first 2 exams because of some crazy werewolf stuff (not going into detail)
- the next day i had a dream where i was making up those 2 exams.

-i had a zombie apocolypse dream
-had one just like it the next day

why wouldn't i pick up on that?
i have never had continued dreams or had the same dream settings
for more than one time.

maybe this will happen more often and it will be a dreamsign for me?
anyone else have this kind of continuation?
i find it impossible to continue dreams when i actually want to.
