I just have a few questions about lucid dreams.

1. Can you actually feel objects?
2. Can you feel pain?
3. Can you feel things that you have never felt in real life? For example, if I want to have sex in an LD, and I haven't had sex in real life, can I still experience it?
4. Do LDs actually feel real?
5. Is there any danger involved with LDing?

If you can answer any of these, thanks in advance!
