Spiral realm
(a.k.a: whirlpool)

one can only be transported into the Spiral realm from any point in the Circle realm.
this transportation is usually a reaction to an event, or change in the subject's consciousness. these occurances are sometimes seen as arbitrary, but their frequency can be increased by certain circumstances, e.g. increasing stress level or playing music for the subject. these circumstances vary widely between subjects.

once a subject enters Spiral realm, they cannot leave and must wait to reach the Centre and be transported back into Circle realm, or another dimension.
