But it's not going to be subconscious, it's all going to be brought up to your consciousness.
The subconscious mind is a storehouse for memories along with the emotional mind.
Think of it like a computer. You have your windows open (conscious mind) and your hard drive with data stored (subconscious mind.) In medical terms it's called the limbic system.
Your conscious mind needs a bit of data, so it goes into your "Driving" folder. Now if there's a car accident file in there it brings up that car accident file into your conscious mind, and that car accident file sets up a feeling and then a vibration.
Nothing in your subconscious mind is going to affect physical reality unless that subconscious thought is brought into your consciousness.
Even if you have a bad car accident memory, if that memory isn't brought to the surface, nothing changes.
