Hello! First post here

So I'm wondering a couple of things;

1. I'm afraid of rollercoasters, which I don't want to be anymore, so I'm wondering if I, in a lucid dream, can "teleport" to my local theme park and try this rollercoaster? Will it be the same feeling? Will I be able to remember it correctly?

2. How often should I pinch my nose (Dreamsign or whatever)?, currently I do it a couple times every minute.

3. What is the average time before someone can start becoming lucid? I know it's very different from person to person but approximately?

Cheers.
