There are a few good things about dreams, should you choose to share your strange dream with your crush. Dreams don't have to make sense, as they're fantasy invented by a sleeping mind. Because you don't have absolute control over what you dream, people tend not to hold each other responsible for dreamed content. Be aware that we often censor who we share our dreams with, too. That's because divulging your dream will likely reveal a lot of psychological symbolism you may not see right away.
If you are going to tell your crush, be particularly cautious of their personal boundaries if the content of your dreams contains sex, violence, or other behavior that may offend your crush. Your crush may not want to know such personal information about you yet. Dreams are intimate peeks at our psyches, and they tell us a lot about one another, much more than what the surface details reveal. Weigh the potential upsides vs. the downsides and consider whether your crush is an appropriate audience for the information you want to share.
