Need Some Advice On My Evocations - Mepsitahl, mepsitahl Options

well Ive done another evocation tonight of Mepsitahl. and I did the full LBRP and hexegram and I used the goetia evocation. the full lot. and the most I get is a brief flash of her from a recollection I had of another time I did it and was messing around and got full view of her., beyond the mirror just after the evocation when the energy is strong after that i see no sign of her. and then I hear laughing? what gives ? ( and this happens everytime I do an evocation regardless of spirit) and then I hear like voices like someone having a conversation in the background but I cant make any sense of it. (I could be trying to hard to hear something and I do that to help manifest a voice. and then just random stuff happens in my mirror like normal scrying and there is no communication. I dont know if that is anough to say the welcome and I cant even check the identity. Is it because she is a fictional spirit? Im pretty new. only a couple years so does anyone have any advice I can try for next time? any help would be much apprecated. thank you

thank you altpath. I know what you mean. but how can you even question a spirit on its identity when its not making clear communication to you. I do seem to get responses sometimes but they are pretty obscure and there isnt really a conversation like talking to it. well im going to do this everynight for a couple weeks. no really. and see if i cant get anything more intellegable
she will definatly hear me than.
I will just record any impression and visions and hopefully it will start to get clearer the more I keep at it.
what are these entities though. they seem like mistrif makers. If they have a sense of hummur thay must be pretty intellegent.
but it seems when you tell them to do something they ingnore you, kind of like kids.

okay I will make another post when I make some progress. peace
