Unfortunately it's more complicated than just changing up word usage as the term "Reality Check" goes beyond these forums and used in various sources for years. Some of the lucid dream terminology and abbreviations might already be enough to discourage some from learning more about lucid dreaming. By changing up a term like "Reality Check" it'll only add to the confusion. I'm not sure this is something that can be fixed especially when the term "Reality Check" isn't fundamentally wrong, it just depends on what reality means to you. I'll start using the term "Dream Check" or something like that when notable people in the lucid dream community such as Daniel Love etc. start a movement. ^^'
