<blockquote>
I once dreamed there was a certain island called the Isle of Dreams. The inhabitants
of this island dream quite vividly; indeed, their thoughts while asleep are as vivid as while
awake. Moreover, their dreamlife has the same continuity from night to night as their waking life has from day to day. As a result, some of the inhabitants sometimes have difficulty
in knowing whether they are awake or asleep at a given time.

Based on their thoughts, attempt to determine if the islanders are diurnal or nocturnal,
awake, or asleep. In some cases you may not be able to determine everything about the
islanders. In some cases, the particular combination of thoughts might not be possible.

<p><em>The inscriptions on the doors can be translated into logical formulae - if you are familiar with the notation, this might help you find out what is behind the doors.
Here "Xd" means that islander X is diurnal, and "Xa" means that door islander X is awake.
If an islander is not diurnal, they are nocturnal, and if they are not awake, they are asleep.

<p><em>There are 4 laws that can be deduced concerning the inhabitants of the island.
<ol>
<li> An islander while awake will believe they are diurnal.</li>
<li> An islander while asleep will believe they are nocturnal. </li>
<li> Diurnal inhabitants at all times believe they are awake. </li>
<li> Nocturnal inhabitants at all times believe they are asleep. </li>
</ol>
Try to convince yourself of each rule, and apply them to the thoughts of the
islanders in the puzzle.
