Unknown children in your dream most often symbolize your inner child, the part of you that wants to have fun, that doesn’t want to grow up and deal with responsibilities. Do you need to pay attention to your inner child and have some fun in your life? Are you being too childish about something?
Unknown children can also refer to a project, idea or endeavor of yours that is not fully developed and still needs your care and focus.
To dream of your childhood or your childhood home can mean a desire to return to simpler times. If your childhood was abusive then this is a good indication you have not been able to move on from issues that began back then.
