Trapped to ex-partner in dreams

I’ve never posted here before. I like to think of myself as a “quiet” practitioner. My great-grandma, grandma and mum have passed down several family rituals that I keep alive. I’ve also been a very vivid dreamer and often use them in a symbolic sense/in conjunction with oracle cards.

Lately, many of my dreams are situations where I am “trapped” to an ex-partner from high school (2005-8). They were my first serious relationship (as serious as high school relationships can be at that time). And they always had quite a sense of possession of over me. We haven’t been in contact for years but whenever I do return home, they somehow find out and manage to get ahold of me. I’ve blocked them on every social platform and keep my online presence rather private, as it is.

In these dreams, I do experience nausea upon waking - I lean a lot into physical signs and it’s as if my body is wanting to purge. I just overall feel really intense and disconcerting energy.

I’m curious if this is something that I should take alternate steps to navigate, as far as this person having sent bad energy my way and/or something worse. I don’t practice spells in my daily practice, but am open to thoughts.

I’ve also considered karmic and soul connections but it all feels off kilter. As of right now, I’ve asked my guides to provide more information, but this seems to result in more intense dreams. Even as I’m writing this post, my phone is glitching and delaying like it doesn’t want to write this out.

Open to any recommendations you all may have. I just want this energy gone.
