I took Ambien for a few weeks and sent some completely insane emails to people and had zero recollection of it. I also made sandwiches and left them around the house in odd places half eaten or not eaten at all. Put the mayo in the freezer and things of that nature. I remember it made me crave cold cuts.
The emails were so bizarre. This was over 10 years ago but I had to stop taking the med.
There are other meds my friend takes that give her completely horrific nightmares, its a known side effect that everyone deals with…fml i forget what med it is…but anyways she tells me about these dreams that are basically like a bad acid trip.
So yea, dreams and dream like states are perfect for implanting things into the subconscious.
