An interesting side effect of the drug Dilantin (Phentoin, Epamin) is that it can produce vivid dreams including LDs. The drug is used for epilepsy and many people with epilepsy refuse to take it because they are not "dreamers" and the LDs freak them out. One desperate fellow said he was terrified of going to sleep because he would find himself fully conscious in the dream world.
