Do you have schizophrenia? This can cause you to feel overly sensitive to the enemy, including having these strange thoughts. It can also make your magic difficult because it changes your perceptions of reality. This can explain why you were having problems.
If this is the case, you first need to go to a regular doctor about this, in order to ground your mind. Then you can go about healing yourself, for which you should pray to Valefor and do yoga and other grounding practices.
Don't doubt the protection given to you by the Gods, but you also have to do your part and void out any thoughts about the enemy, even if this is difficult. Your healing may take time and this is normal, but it is much easier and better for you to heal your mind and soul, rather than try forcefully astral project or permanently enter a dream world.
