This is a two-part question. First, why is it that when you turn on a fluorescent bulb it flickers before it fully glows as compared to an incandescent bulb that glows instantly when you turn it on? And second, is somebody working on a fluorescent bulb that doesn't flicker before fully glows?

It was late at night and my bf was trying to call me, but I didn;t hear my phone, so he had the downstairs people come bang on the door, but I didn;t hear that either. A minute after they quit, he called again and I heard it and he asked why I didn;t wake up or something and I said I didn;t even know, but I just had a dream that someone was banging on the dorr and I opened it and they tried to come in and I called the police, but that really didn't happen though, but I dreamt that while they were banging on the door. So, what exactly cause this and why? I mean, I dreamt what was happening kinda of with a twist of calling the cops. What causes this and why? Has this happened to you?

I manage a drive-in movie theatre so I am very aware of what time it's dusk during the summer season. Over the entire summer, dusk time changed by no more than a few minutes from week to week. However, a few weeks ago I was at the drive-in on Sunday night at about 8:45 and it was just barely dark enough to start the movie. By the following Friday (5 days later) it was suddenly dark enough by about 8:20.

Can anyone shed some light on why dusk time would change so drastically in just a few days when it normally only changes by 5 minutes over a week. Could it has something to do with the sun's position relative to a distant mountain range or something similar?

For what it's worth, I live in northern California about 3 hours north of the Bay Area.
