In that case I would recomend making a "night terror kit." Put together a bag filled with things that you can do until you become calm again. Maybe some snacks and a bottle of water, just for a few minutes so you can get back to normal and mayb fall asleep again.
I dont think something is following you, but what are the physical things that have happened? Your nightmares could be someone trying to get through to you, or your simply just scared. If you have anxiety or stress that can also effect your dreams, even eating chocolate or cheese is said to give you nightmares. If there's things happening in your home, things been thrown, moved, people being pushed, flickering lights etc a spirit could be in your home, and its energy might be affecting your dreams. There's a number of possibilities why you have nightmares.
Ive been shoved off a bed, scratched on my arm, pulled under the bed, , door slammed in my face, my back pack was on the ceiling (this was one of my first encounters)
fan somehow it was holding on to the fan and went faster and faster and flew off on my chest while i was sleeping, I woke up and the backpack was on my chest and it hit so hard it took my breath away.
Oh I'm sorry all that happened! Try banishing negative energies or spirits, there may be a spirit that's in your home or "connected" to you, that could by why you have nightmares.
Yeeek! Scary stuff happening to you! While I'm not sure what to do about the night terrors, for the physical stuff I would STRONGLY suggest some Sage and warding of your space. Get friends to help if you can, as the more people helping you, the more energy raised to fight this thing off. I've lived with a nasty spook before and it's no fun. It would cause me to see corpses in my home and try to scare me off. I went a bit nutty until I moved. Now no more problems, though it likes to bug me time to time.
Tar Water is supposed to be good for stuff like protection. The idea behind it comes from the Middle Ages and is supposed to be quite powerful. You can find the directions to how to make your own Tar Water (or purchase it) here: http://ghostsofarizona.webs.com/terminology.htm
Im new and dont think any spells will work for me yet. Im still doing research on how things work, different paths, auras, chakras, all that good stuff. But I will copy down some repellents. After 20 years id really like to break from whatever bad spirits I attract. Lol.
Reg thank you for the advice, I will try the sage! And Conjure this has followed my since I was about 4 or 5. Not sure why, I never had any trauma before these things happened. Im extremely sensitive to demon type stuff though. And almost anything opens a door to let it in and I just have to fight it the way ive learned. I would quite like for it to go away forever though.
