Can you escape?

A room in a beautiful inn. The room called 'Higan' is cursed. If you stay in that room and sleep, you will surely see a mysterious dream. If you escape without being caught and wake up safely, you will receive 2 million yen as a reward.

However,

If you are caught by someone in the dream, you will be trapped in the dream and never wake up again.

Such is the legend of this inn. After checking in and being led to Higan by the landlady, you find a room so spacious it's hard to believe it's free.

The landlady speaks.

Beneath this room... this place is where a tragedy occurred long ago. Those who have woken up in this room can be counted on one hand...

...It would be a help to us if you could see what is happening inside the dream—or more accurately, what has become of that seal.

If you do wake up, the reward will be automatically transferred to your bank account.

Well then, please make yourself comfortable.

The sound of a river flowing can be heard; it is a calm, ordinary night.

If you get into the futon and sleep, the dream will begin.

Now, what shall I do?
