You could call this the positive feedback of negative vibes, but I think in something so spooky, we really shouldn't have the word positive there at all, even in a technical sense.
Putem numi asta raspunsul pozitiv al vibratiilor negative, dar cred ca in ceva atat de inspaimantator, chiar nu ar trebui sa folosim termenul de pozitiv deloc, nici macar in sens tehnic.
