What does it mean when you dream about a guy during the night?
Discovering what dreams mean is very complicated business. There are dozens of books on dream interpretation, but there are also dozens of studies that suggest dreams don't have secret meanings at all; at least not ones we can discover by using a book or talking to a dream specialist.
If you really want to know what your dreams mean, it's probably best to simply ask yourself what YOU think they mean. Consider how the dream made you feel. Consider how it makes you feel when you think about it when you're awake. Consider anything in your dream that seems strange or out of place. Or else, don't consider anything at all, and just use your gut feeling.
If you think it means you are interested in him, you probably are. If you think it means you are threatened by him, then you probably are. You get the picture. It also depends on what kind of dream, if you fall in love, kiss, makeout or hold hands with him in the dream then you probably shud go after him.
