A very warm welcome to you @moon! 
I hope you don’t mind that I moved this post into it’s own post so it can get the attention it deserves- hopefully your new forum family will have lots of advice and guidance for you 
It does sound like a scary situation- I’m glad you had your trusty companion Sonny with you! 
It is also wonderful that your parents are supportive of your beliefs- you are surrounded by good presences and the light of your loved ones 
Kasie offered some great advice- I would definitely start with a Protection Spell. It will help you feel safe and relaxed as you move forward with figuring out what is going on :thumb:. When the protection spell is in place, you may want to consider using Divination (such as tarot, pendulum, tea leaf readings, or other methods) to try to gain insight about who or what this presence is 
Wishing you the best of luck, Olivia! Please keep us updated- blessed be!
