Dream about someone having twins is a premonition for missed and lost opportunities. You are preventing certain negative emotions from surfacing. You are lacking a certain aspect or quality that the loved one embodies. The dream is a symbol for some aspect of your relationship with your sibling, whether it one of sibling rivalry, nurturance, protectiveness, etc. You feel that you have no control over your actions or are not taking responsibility for them.
Someone having twins dream is sadly a warning alert for unpleasantness and coldness amongst your social and business circle. You may be giving off a false impression and passing the views of others as your own. You are entangled in some emotional matter which you are not sure about how to get out of. The dream points at the negative aspects of your childhood. You are losing control of who you are.
If you dreamt about someone having twins:
It is not that you can’t decide whom you like best, as you like both of them the same. It is just that they both have features that stand out, and which make you want to love them equally, rather than being bold enough and brave enough to come to a final decision.
