Letrozole and dreaming

I hesitate to point my finger directly at Letrozole, but I have far more vivid and distressing dreams than I did before I had BC. Is it menopause, or mental distress, or directly as a result of taking Letrozole, I don't know. What I do know is I wish it would bloody stop...

I doubt it's actually the drug. ..but here are my thoughts.
BC diagnosis impacts on our sleep pattern..and especially if your sleep is particularly affected by hot flushes etc. Now...can you recall being woken in the past mid dream by someone. ..you vividly recall the dream happened. So if your sleep is disturbed by treatment or stress of diagnosis. ..then being aware of your dreams is more likely.
Women can have some PTSD type symptoms from treatment also which can include dreams. 

It might be an unreported side effect. I know although I sleep better now I certainly used to sleep much lighter after bc treatment and any noise woukd wake me. 

THank you both, I did find one or two references to dreams online but my McGrath nurse thought it might be processing all thats happened over the last few months. It does seem to have settled, still dream but not as vivid or memorable. Might be a good time to find someone to talk to.
