  We further explore the idea that physics takes place in Clifford space which
should be considered as a generalization of spacetime. Following the old
observation that spinors can be represented as members of left ideals of
Clifford algebra, we point out that the transformations which mix bosons and
fermions could be represented by means of operators acting on Clifford
algebra-valued (polyvector) fields. A generic polyvector field can be expanded
either in terms of bosonic, or in terms of fermionic fields. In particular, a
scalar field can transform into a mixture of bosonic and/or fermionic fields.
