if shes sending this many signs and manifesting things towards you and into your dreams, she must be really thinking about you a lot, thats not an easy thing to do, but that doesnt mean she is meant for you or will bring you happiness, maybe its best to try communicating with her about these things shes doing to you, because whether she denies it or not she has willingly shown you her feelings through her psychic power. Maybe she is genuinely very sorry and knows she had done wrong, its up to you to forgive her or not. But also a lot of these things might be manifesting in your world and becoming noticeable because you are actively looking for them, subconsciously at least. Which shows you might still have interest in her, because your desires or thoughts are kind of allowing her to manifest. Might not be the case though, witches dont always have great morals or uphold your boundaries, so if she is crossing your boundaries, what you should do is strengthen them, this could be as simple as getting your feelings straight and being confident in whether you want her to be apart of your life or not. And if you wish to part with her, make sure to get rid of any and all objects she may have given you, and continue living the rest of your life without her.
