Lol, I think 27 is a perfectly acceptable age to become sagely!

My interpretation of it is that there's something in your past left unfinished, or someone you feel the need to reconnect with? I swear that's not based on past conversation, it's really what I think that dream would be saying. The house representing the past, boarded up likely indicates something you try not to think about, and pets could indicate people easily. I'm not exactly a sage, but that's what my intuition on it is.

Or it could just be a dream your brain is use to having? Not all dreams are "mystical". Though trust your instincts if it is or not. If you've got that nagging feeling, well it's probably right.
