A dream isn't lucid unless you control it
There is some confusion about the difference between lucidity and dream control. The two are related, but one can happen without the other. For example, many lucid dreamers experience little or no control in some dreams. On the other hand, it is possible to exercise some dream control without being aware that it is a dream. Typically the dream plot will explain this by making the dreamer believe that they have some sort of god-like power over everything. Dream control, by our definition, can be either conscious or unconscious.
Lucid dreaming is new age
Because almost everyone has lucid dreams naturally every once in a while, we know that lucid dreaming is not limited by any one viewpoint. There are historical records which speak of lucid dreaming going back thousands of years, so it is hardly a new phenomenon. There is no need to have any spiritual beliefs to enjoy lucid dreams.
Lucid dreaming advocates escapism
Lucid dreaming occurs while you are sleeping; it is not meant at all to infringe upon your involvement in the real world. While many lucid dreamers enjoy writing down their dreams, talking about their dreams, and planning fun lucid dreams, this is generally no different from any other hobby. In fact, playing a video game or watching a movie will take you out of the “real world” more than lucid dreaming will.
Lucid dreaming is unnatural, involves "dark arts," or is occult related
Many religious or spiritual sects lump lucid dreaming in with occult practices and activities. Lucid dreams often occur naturally and there is nothing occult about them. On the contrary, many great religious epiphanies and messages came in the form of dreams; sometimes lucid dreams. Our dreams are what we make them; whether we wish to give them spiritual significance or not is up to us.
Dreams contain messages that are lost with lucid dreaming
As of this writing, there are many theories about why dreams exist and what purpose they serve, but so far none of these theories has been proven. One theory is that our dreams contain important or useful messages about our lives. Considering that many people do not even remember their dreams, let alone pay them any attention, changing the dream plot in a fraction of one's dreams is in comparison not nearly as problematic for any message-sending done through dreams. Lucid dreaming also requires very good dream recall, so even if a fraction of these messages are lost in lucid dreams, you are likely remembering many more regular dreams than you ever did before, and on top of that, giving them more attention than ever. Lastly, if we consider that it is our mind that gives us the message through dreams, even if lucid, there is high chances that the message will show regardless.
