i always see mcs get wish without nowhere , suddenly become op so this is just my imagination btw
what if rob(random overpowered being) need energy ,such dream Energy??
and that dream come from human ?? then that MCs die but he didn't get reincarnated but illusion which seem he travel multiverse and get harem but it's not
by this ,that illusion release so much energy of dream because that MCs life in place what he want(illusion) which he didn't know that .
so as you know maybe half mc we read was in illusion rather than reincarnated
which make me feel cold ,to think maybe it happen to me
btw suggestions for power that you want to know today ,cause it's already evening which I have time to write
