Does taking Seroquel XR cause vivid dreams? Has anyone else had any experience of this?

I only take 100 mgs about 3 hours before bed. For the past month or so, my dreams have been very vivid, very easy to recall, and sometimes rather disturbing. Not nightmares exactly, just... intense.

I've been on meds since the end of January--300 mgs of Effexor XR in the morning, 100 mgs of Seroquel XR at night, and hydraclorothyazide and lisinopril for blood pressure.

I can't tell if the dreams are from my issues being stirred up or from the meds. Any thoughts? Thanks in advance.
