Your Stage : Logline opinion by A. M. Sherif

Hello guys! Can you please tell me how good/bad these concepts are? "A bereaved girl uses an experimental device to access parallel universes where her family is still alive. But losing her grip on the real world means her death." "A detective hunts a serial killer who uses illusions to kill his victims. Hunter becomes prey in a world where reality bends in deadly ways." Thank you so much! P.S. I'm a big fan of co-writing. So, if anyone wants to co-write in a project of mine or his, please inbox me.
