I have had similar events.
Once in a while I have a very surprising moment.
I have dreamt certain things before. And those images come flooding back to me at a certain obscure and seemingly random moment. I take it as a sign that God has put me in the place I am currently in and He is in control.
The dreams are sometimes vivid and sometimes vague. But they always seem to have that familiarity.
Scripture says, about the last days, that during that time, “Your old men shall see visions and your young men shall dream dreams.” Perhaps God is trying to persuade you that there is more to life than your mundane every day “matrix-like” existence.
Perhaps you should take the pill and see how deep the rabbit hole goes. =)
What do you have to lose?
