Upright:

It is a time of nostalgia and happiness. You may be taking a stroll down memory lane, but be sure that you aren't avoiding your current situation by getting lost there. Take a breather by remembering better times but be sure not to dwell.

Inverted:

You may be having troubles with childhood, possibly with children in your present time or with spending too much time dwelling on the past. Revisiting cherished memories is important but you might be spending too much time there. It's also possible that you have an unrealistically happy memory of past times.
