I might be a little question but I don't think I would be able to give it a comprehensive answer. So many details are involved. It kinda like answering "How long is a piece of string?".

One part of it is like walking through a jungle that is the home to many many trip wires. You never know when you will step on a trip wire and it all happens so suddenly when you do. The moment you step on an invisible trip wire a switch gets flicked on and somebody else inside pushes their way to the front. For me that means my speech changes and I may or may not remember what is said. My control goes out the window.

That's my perspective.
