Hey! So I keep finding bones (mostly skulls) on my walks when I never found any before, I have a repeating dream about a dried dead river bank and a creature that lives in it. It’s like a rotting cat.
Now, I’ve been getting an urge to summon something, but I don’t know why or who? It’s strange. I never felt compelled to summon anything before.
Are there demons who are attached to these things I’m experiencing or am I just reading into it?
Thanks for any help given! 
I’d suggest a good banish and cleanse just for safety’s sake to start with, and set up good wards so tat you’re not being influenced by astral randoms against your will.
Invitations from entities are usually less invasive and you see signs that you can associate with, or know clairsentiently that they symbolize the entity.
Then decide how you feel and if YOU want to summon if you’re into it, ok… then ask yourself what you need in life that would be beneficial for you to work on, leaf through a grimoire and see who does that, and call them.
