I've always felt that dreams told me something, not necessarily in a "voice of God" kind of way, but more of an on-the-nose metaphor kind. Dreams are your mind's way of processing what happened to you during the day.

If I can throw some questions at you: Is there anything about the meds themselves that scare you? Anything that would make you think they are toxic for you (in the metaphorical sense)? What's the (proverbial) poison?

Hope that helps somewhat.
