In the trish's dream diary, you will face a series of events based on symbols, each symbol means a type of encounter as follows:

-Skull: you will fight a random enemy.

-???: you will find frogs, a calm corridor or hands in the walls.

-€€€: A shop with 4 items.

-A red triangle upside down: bossfight.

The sequence of events seems unchanging, but the individual events are random(not the case for shop or bossfight).
