What do you think about this...
So I've never read this forum before or heard anything about Aspirin causing dreams... however, I just started a low-dose aspirin regime and I started having vivid dreams (VERY unusual for me) every night since I started 2 weeks ago.
Because of this peculiarity I decided to Google Aspirin and Dreams and came upon this forum... soo I'd say that kind of rules out the placebo effect.
While this effect may not happen in the general population (I would guess there would be lots more info about since it has been a common drug for so many years) it does seem to be real. Perhaps those of us who experience this effect are all genetically similar in some fashion that is otherwise rare.
