I've been taking sudafed for a few days for a chesty caugh and I have been having vivid scary nightmares where I've been kidnapped by terrorists and attacked at random in my dreams, turning them into a nightmare, I decided to read the sudafed leaflet and it states
"May cause bad dreams and hallucinations"

Usually when I have nightmares they are not really scary, or scary in the sense watching a horror movie is scary, but these dreams seem like its really happening to me. Nightmares are usually rare for me, and I can usually become lucid or wake myself up when I do have them, but I'm trapped in these dreams.

so has anyone had any other dream effects with medication or experienced anything like this?
