You are obviously under some kind of an attack by entities that wish to keep you filled with fear. I am including a link to a topic on Archangels
and I would like you to read the topic on Archangels Michael, Uriel and Azrael. They are very strong protecting angels. You may also wish to look into learning about smudging your home. Here is a link to a list of members who can help you with this Smudging Links. Having an epsom salts bath can help rid you of their connection to your spirit and body as can a cleansing ritual that is mentioned in the Archangel Michael link. I would also put epsom salts around your doors and windows. You have to ASK angels to come to your help. They cannot help unless they are asked due to non interference in our free will choices. I also suggest that you contact Trevor Lewis for some further insights as he can help with cleansing issues. Please let me know how this progresses. I will include you in my daily prayers to send you Light energy.
Throw some love into the wind.
Going off meds can affect your dreams for quite a long time, depending on how long you've been taking them. That's a purely physiological response that will pass, if that's all there is to it. Sleep meds will prevent you from dreaming or remembering dreams while you are taking them.
Interesting page about seeing faces before sleep below.
Rene' twenty years is nothing to this kind of attachment, or dark energy, its purpose is to disrupt your life in any way possible. In my opinion this entity can't really hurt you unless you let it, which means letting it drive you crazy to the point where you want to hurt yourself.
I don't know what religion you are but these kinds of energies do respond to being cast out especially by Catholic Priests, that's totally up to you. As Bing said pretty much above they rely on the Arch Angels to cast out the darkness in the event that you can't.
