I got a new, high pitched sound at bedtime 2 nights ago. I honestly thought it was something in the house...but my family didn't hear it, just me. The next day the sound was gone. But at bedtime last night, there it was again. This afternoon, it appeared again. With that tone, there are other ones...a sudden higher-pitched one happened for a few seconds, and some mid-pitched tones as well. How do you adjust to new sounds bursting on to the scene? I've been having a hard enough time trying to cope with the sounds I've had for a while, and then having new sounds appear...Grr.
