Sure. Isn't anything we observe like that tied in with physiology? How else do we experience motion of the feet, for example? Mahasi-style teachers (such as the ones I've done retreats with) would say that it has to do with experience of air (motion) element and it seems like a reasonably common thing. http://buddhanet.net/vmed_4.htm

That's why we take these compounded elements for a personal being, an I or a you, because we can't divide. Our intellectual knowledge is not enough to penetrate into these elements, and realise them in their true nature. So we think this is a body, this is a mind, this a man, this is a woman, this is a leg, this is a nose, this a hair. If we have penetrating insight knowledge through our vipassana meditation, insight meditation, then we can penetrate into these primary elements and know them and their nature and also their appearance and disappearance, and the nature of transitoriness of these elements.
So here when you practise walking meditation you feel that you are walking on a boat which is floating on the waves of the sea, or as though you were walking on the air, or as though you are walking on a heap of cotton. You are realising the specific nature or specific characteristic of the wind element vayo-dhatu. Vayo-dhatu, the wind element has movement, motion, supporting, vibrating as its specific characteristics, or individual characteristics.
Normally we do not realise it. But when we watch the movement of the foot while we are walking very closely, attentively and precisely, then our concentration becomes deeper and deeper. Then, because of deep concentration the insight knowledge or experiential knowing becomes penetrating and sharp. So that penetrating insight realises the process of movement and its specific characteristics of movement, motion, vibrating and supporting. So we feel we are walking on the air, or we are standing on the boat, or on the waves of the sea. Because the waves of the sea are always moving.
And many people describe the experience after several days of sitting doing Goenka-style body scanning that the body feels like it's breaking up. Goenka talks about it, and that was my experience. I seem to recall Retro and Ben discussing this back on E-Sangha when Retro did a Goenka retreat several years ago. I think there was also some discussion here.
Of course, I would say that one should be very careful about assuming that what one experiences is anything special, since all kinds of odd stuff can arise in meditation and it's easy to assume that it's more than it really is...
