I’ve had dreams of having OBEs before too.
I’ve seen that I tend to dream about anything I focus on intensely. When I first began trying to have OBEs, I had my first dreams of OBEs.
Dreams of OBEs are difficult experiences to categorize. They’re probably best thought of as false lucid dreams, unless of course you know that you’re asleep and dreaming and dreaming of having an OBE (then it’s simply an LD).
I’ve had dreams of OBEs where I’ve noticed that I “left my body” in a different place than I actually fell asleep. So, in those dreams, I went lucid, I guess you would say, when I noticed this. However, non-lucid dreams of OBEs are definitely more vivid than ordinary non-lucid dreams. Usually, you act as you would in an OBE. You act as if you had lucidity, but you’re missing (arguably) the most crucial piece of lucidity: awareness of where you really are.
By paying attention to dreams of OBEs, I’ve noticed that they’re phenomologically quite different from actual OBEs.
First, in dreams of OBEs (at least for me) it’s ridiculously easy to “leave my body.” In a dream of an OBE, I pop right out, whereas OBE exits from the waking state are much more difficult.
Second, in dreams of OBEs, just like in non-lucid dreams or lucid dreams, some form of “gravity” is usually operating on the environment. Personally, in my OBEs from a waking state, there’s no gravity to speak of.
An intriguing point of view that I came across recently is that dreams (lucid or not) are really a subset of OBEs. In any dream we aren’t really inhabiting our body sensorially, but we’re focused away from our bodies in a mental environment. In other words, in a dream you aren’t directly experiencing your body or your body’s environment; you’re experiencing a mental body and a mental environment. This isn’t to say that all dreams are truly technically outside of the physical body–just that dreams do not have a physical sensorial focus.
