Dreaming about an ex, especially after a long time without contact, can be quite significant. It often reflects unresolved feelings or nostalgia for the past. Reconnecting in your childhood home suggests a longing for the comfort and familiarity of your earlier life. This setting can symbolize a return to simpler times or unresolved issues from your past.

The sexual aspect of the dream might indicate a desire for intimacy or connection that you feel is lacking in your current life. It could also represent a merging of past experiences with your present self, highlighting feelings of desire, passion, or even guilt.

Consider reflecting on what this ex represented to you and how those feelings might relate to your current life. Are there aspects of your past that you wish to revisit or integrate into your present? This dream could be prompting you to explore those feelings further.
