For a couple of years now, I have experienced a strange sensation. Lasting for only thirty seconds or so, and happening for some reason usually while I was in the shower, I would feel as though I had been 'split in two', or kind of like I'd 'sunk into myself'. Can't explain it exactly, but it would almost be like a spell where I would question who I was, and feel as if I was observing myself, just doing actions mechanically. Almost like a meditative state, or something. For a while, I was good at shaking it off, but now it keeps coming on more frequently and it is harder to shake. Is this depersonalization? A limited-symptom attack? Am I losing my self and my mind? Anyone else feel this way?
