A) There is not always a task, at least from the beginning. Sometimes you end up in a weird place and you're like, "Why am I here?" Then your mind creates a task for you, so you don't realize that the entire world around you makes absolutely no sense.

B) Dream time is very close to real time. In EWOLD, LaBerge explains it in detail.

C) Yeah, read the tutorials and everything before posting.

Sorry if I sound annoyed. It's because I am. I know you meant to help.
