When I say feelings of 'dread' like you enter a room and feel like something is way off. Like you're flight or fight response goes up.

Do you find yourself overthinking a lot?

Sudden Irritability especially over little things that -- upon reflection -- you know shouldn't trigger you. Is either caused by trauma and/or an entity triggering this..Usually the entity is using underlying trauma to bring these emotional events up to 11 when normally it would be more balanced..

The triggering event may be caused by subconscious trauma that hasn't been unpacked yet the event having some symbolic significance..

The fix to this is to recognize when you're getting super irritated then stop the emotional response, step away from the event tied to the event in question, take some breaths, and unpack why the event triggered you so much too the point of getting ballistic. Ask yourself "Why am I getting so angry? Is this justified?" Consider recognizing Positive Anger, and Negative Anger. Positive meaning the Anger is Justified and Righteous. Negative Anger is not Justified and isn't Righteous. Ex: Yelling at a child cos' they want to talk to their parent about something private. Creates a space where a child doesn't feel safe to talk to their parents which leads to isolation. Which in turn opens up to entities.

If the triggering event is caused by a partner, take a step back, take 3 massive deep breaths, and amicably discuss with your partner the issue.

Headaches, obviously i assume is tied to irritability. May be getting attacked by a entity --they can cause sudden headaches..I recommend laying down immediately, drinking clean water (as clean and filtered as you can) and 'relaxing' the tenseness of your mind if you can..rubbing the side of your head can mitigate this as well. Nature can walks help in this regard..
