Ahem:

Q1: People have dreams that seem like they last hours. To paraphrase Laberge, "It's like a movie, where the main character has gone to sleep. He turns the lights off, we see a few seconds of darkness, and then it is the next day. We perceive that hours have passed, but really only seconds have."

Q2: I have never had trouble waking up, but it's probably different for everyone. You have to remember though, that you are simply asleep, and will wake up in the morning.

Q3: Never happened to me. Remember, nothing can hurt you in the dream world. There you are not governed by fear.

Q4: No idea what you're talking about.

Hope this helps!
