Dream chronical2 Labyrinth

I have the map of the labyrinth but I cant figure out how to find anything other than 1 key .There are no marks telling where you are .I have tried the game twice.The first time 6 months and just started again.I cant even find the entrance again.Pleeeesase help.Thanks

The walkthrough shows the map and it's marked as to where the entrance is and where all the items are.
