In reading various accounts of lucid dreaming, it has occured to me that what I have taken as standard in my lucid dreams from day one, may not be standard for other people. I'm a relative novice with only about 20 lucid dreams under my belt in the last four months, but I almost always fly. It is usually the first thing I do when I am lucid. The other thing is that it has never occured to me to open doors or windows to go through them. I just naturally walk right through them without bothering to open them. This isn't something I think about, I just take it for granted when I am lucid. I'm just wondering if other poeple find these types of thing standard, or if they have other lucid dream affects that they take for granted.
