According to modern observational data the phantom equation of state for dark energy is not excluded. This scenario creates problems with stability of universe evolution. An alternative to phantom models is given by models of scalar matter with non-Hermitian, PT-symmetric interaction. We present the set of such models with several scalar fields which are exactly (analytically) solvable both in classical and in quantum case. The latter case is investigated in the FRW minisuperspace approach. We use advantages of analytical solvability to disentangle the differences between phantom and PT symmetric dynamics and give a favor to the latter one.
