AnomalyEtt l�gt brummande ljud som �r sv�r lokaliserat men som jag tycker �r bakom �ronen och bakhuvudet. Det kommer bakifr�n inte framifr�n. Jag h�r inte det h�r ljudet hela tiden, utan det kommer inbland och varar en liten stund, olika l�nge. Jag kan inte se hur eller varf�r ljudet uppkommer, det bara finns d�r helt pl�tsligt. Det kommer inte fr�n n�got h�ll utan det bara finns.
