I just figured it out. You need to complete a fetch quest consisting of a few tasks. The quest starts after you save the kid from the well, then you can talk to him and take some ,,Straws''. After that u need to use the straws to save a dawning person ( on a different map in the city ) - He will give u the next item needed for the quest as a reward. ( u will get the name of the next map u need to go after u take each item , use ,,Q'' to open the dialog window if u missed it ).
So basically u need to find Straws then Talisman, Oranges, Cloth,and a lottery ticket. Then trade the lotery ticket for a horse, and speak with your landlord ( the old person next to your house ). He will give you access to his hut in exchange for the horse - and his hut is actually the reminiscence hut.
Just follow the hints and/or look for people with bublles over their heads around the city.
