Torsion in a 5D spacetime is considered. In this case gravitation is definedby the 5D metric and the torsion. It is conjectured that torsion is connectedwith a spinor field. In this case Dirac's equation becomes the nonlinearHeisenberg equation. It is shown that this equation has a discrete spectrum ofsolutions with each solution being regular on the whole space and having finiteenergy. Every solution is concentrated on the Planck region and hence we cansay that torsion should play an important role in quantum gravity in theformation of bubbles of spacetime foam. On the basis of the algebraic relationbetween torsion and the classical spinor field in Einstein-Cartan gravity thegeometrical interpretation of the spinor field is considered as ``the squareroot'' of torsion.Comment: 7 pages, REVTEX, essential changing of tex
