Vivid dreams on IVF Meds?!?

Tonika
Hello ladies,
I am currently on day 8 of STIMS;(follistim, menopur, and I was on Femara for 5 days). We started ganirelix last night. I started having vivid and somewhat disturbing dreams. I'm already stressed out, because I have high FSH I'm 39 and the Doc only saw 5 follies which we expected. I am still very nervous I keep reading all of these different Blogs and watching YouTube videos looking for comfort. I'm searching stories that had good outcomes, I have found a few. There are so many more horror stories about different things that have gone wrong...I guess my imagination is running wild because I am having horrible dreams! 
Is this normal? I can't seem to find anything that states that the medication causes one to have nightmares or vivid dreams.
Has anyone else experienced this or are you currently experiencing this?
Or am I just crazy...
