I've been reading through this thread for a while.. and what happened to you, Glowworm, is very similar to what happened to a friend who started spirit keeping a year ago. She has a powerful imagination, and was looking up different types of spirits and spent time thinking about them and what they could do.
She started to freak herself out. She created her own thoughtforms, started to see the things she created. These thoughtforms haunted her, took over her mental state of mind, and she believed that they were outside entities. How I figured out they were thoughtforms is because she created them and their backstories much the same as she would create original characters. Also, they never interacted without her behind them.
Aurum reminded me of this happening, and I see it now with what you've been talking about. What helped her is by taking a break and to re-evaluate herself and what was going around her. As well as trying to take herself out of the situation at hand (as she did not have a very... positive atmosphere she was living in). Don't give up on your spirits, and don't give up on yourself, either, but definitely take some time to breathe and think things over. I suggest to do research into thoughtform creation / uncreation, as well as to contact your original conjurers for further information on your spirits, as you might be perceiving them in a way that was not meant to be.
If I can, I want to help anyone with the background experience of seeing what my friend went through so they don't have to go through similar.
A year later, she's got three more spirits and a lot more knowledge about herself, and what she can do, and who she is, and how powerful her imagination and creation can be. You can make it out. I believe in you.
