We demonstrate a simplified version of quantum mechanics in which the states are represented using real numbers only. The main advantage of this approach is that the simulation of the $n$-dimensional quantum system requires $n^2$ real numbers, in contrast to the standard case where $n^4$ real numbers are required. The main disadvantage is the lack of hermicity in the representation of quantum states.
