Wow, that is one strange and detailed dream.

I don't believe in the whole "dreams have meanings" thing. I think sometimes they can, but I think it's more when someone from the other side (someone who has passed) visits you, which I think is possible. In fact, I had one last night that my friend (who passed away in FEB) was in. I felt like he was visiting me.

I don't really know why you would have a dream quite like this, but are you on any medication, and if so what kind? You could be thinking that the medicine you are on is trying to take away your thoughts and turn you into a zombie (by zombie I mean mindless not the Hollywood kind) which is something a lot of people on anti-depressants feel. I am not sure though. It is definitely a strange dream and you'd probably do better talking to a professional, your therapist maybe? If you have one?

Other than that I don't have much to offer but that is definitely one strange dream. Also, did you happen to watch a movie that day? Could have explained the credits and stuff.

Hope I helped some!
