We consider the possibility that some events from the gravitational wave transient catalog can be linked with mirror world theory. Some theories of star evolution predict the existence of upper and lower mass gaps for remnant compact objects. GWTC-3 includes some odd events that fall in these forbidden mass intervals. In order to explain these challenging signals, very specific assumptions are required. We argue that mirror world binaries could be good candidates for these gravitational waves. Mirror world seems to be dominated by helium, encouraging formation of heavy stars at early times and as mirror matter abundance can exceed ordinary matter density, merger rates can be amplified, promoting a hierarchical merger scenario. Absence of follow-up optical radiation supports this suggestion.
