Signs of demonic activity

i understand spirits lie and i know that they give false names sometimes but i know this is the real deal because i summoned Lucifer from his sigil also i have never felt a spirit so Powerfull as that spirit and i know that spirit is Lucifer because he helped me and i have read that Luciferians (i mean the ones who practice luciferian witchcraft)also wants to be exactly like Lucifer and they call that enlightment im sorry i changed the topic i made a new one as you sugested is called "about Lucifer" you are probably right probably it is a lie from a spirit but from my research probably its not a lie
