The house represents a life that you could build with your girlfriend. Note that the dream does not determine or foresee any specific future, but it does express your hopes and emotions about the future.
it means you do not trust your girlfriend.
A dream about building a house of caves for the devil sounds like a figurative description of attempting to bury unpleasant aspects of the dreamer's own personality.
If you dream about having a girlfriend, it does not necessarily mean that your man is straight; it could be due to your fears of finding out that your man is not straight.
The dream probably expresses your jealousy or feeling of being inadequate to hold the girlfriend's interest.
It more than likely doesn't mean anything; a dream is just a dream. Don't hold your girlfriend accountable for something you dreamed happened.
The dream expresses your own desires and emotions. It does not predict the future and it does not reveal your girlfriend's thoughts or feelings.
that you dont like his girlfriend
This dream illustrates your own feelings about your girlfriend rather than revealing her behavior or intensions. You might suspect that she is cheating, and the dream reveals your suspicions. That does not mean that she is cheating.
That you have not yet moved on.
maybe because you want to be with her in that moment.
The dream expresses your own emotions. It does not provide any information about the guy's thoughts or feelings, or those of his girlfriend.
it is trying to show you how much you mean to her :D
