I have been playing drums for a few months shy of a year now, i must im a helluva lot better then i was 10 months ago, but anywho, every now and then when i go downstairs to "bang away" for a lil while i hear voices, they call my name and scream at me while im playing but when i stop and come upstairs to see who is yelling there is noone there i honestly think im either going crazy or my new house is haunted.  its mostly when i hit my snare that i hear the voices but i also hear them on just about every drum i have... just not as often... its been happening for ab out 2 months and im honestly starting to get scared to go downstairs and practice and its really startin to piss me off.... any advice for the mentally deranged?
