I've never been able to remember my dreams but now i do. can it be bc i'm taking antidepressants now.?

Yes : Changes in rem sleep on antidepressant s can enable you to remember dreams more.

Yes.: Particularly when one starts taking or increases the dose of an anridepressant that increases serotonin, dreams can be much more vivid and more accessible to memory.

Maybe: Antidepressants can make your dreams more vivid, possibly helping you remember them more easily.

Possibly: More vivid dreams are a frequently reported effect from many patients who take ssri's and/or other medications. It might be good to mention it to your doctor - especially if you have a problem with it - but in any case. Best wishes for feeling less and less depressed and learning more and more about yourself.
