My ex, Mel, thinks it’s all to do with being hypersensitive to variations in the diurnal energies, and I’m inclined to think there might be some truth in it. If so, and if you’re sensitive to them, it would mean that those energies would sweep you to one shore in the morning, another in the afternoon, yet another after dark, and a different one again around and beyond midnight. That’s how it feels.
I think this might have something to do with living alone and having little contact with people generally. If you live with a partner or in a family unit, and if you go out to work and to socialise and so on, the routine presence of other people keeps you constantly making a subconscious effort to walk a middle line. To use the classic phrase, they ‘keep you centred.’ That’s because in order to interact closely with those people you need to be relatively consistent, and so you resist the natural pull of the energies. If you don’t do those things, however, you don’t need to make the effort and consequently get thrown about all over the place.
Alternatively, you might just be mentally ill.
