no, no, no, crazy you are not
i would say that you were crazy if after experiencing all that you have you have you didn't put your faith into Jesus Christ, that IS insanity
on a personal note:
i have had similar experiences, as a child i saw a type of silhouette of a demon on my wall, the light was hitting certain areas of my poster to make it look like a demon, well, i was raised in a christian household, so i new that if i prayed in the name of Jesus to remove the evil, that it would be gone, so that's exactly what i did, when i prayed i closed my eyes, and when i was done i opened them, and the image had changed to one more like what we think Jesus looked like, personally i don't believe in coincidences anymore, and now i see shadows that move by themselves, once in a while i see strange lights moving around too, but not as often, then there was the time a lady came into the store i work at, she was looking for some kind of strange book, and i'd almost swear that as she was walking up to me, her face changed from being tan and ugly, to lighter and normal lookin', and she asked for a book that i'd never heard of, and one that no one has ever asked for since, and i've been at this store for 4 years now, so i'm pretty sure it's some kind of evil book
on a more general note:
the spiritual realm works differently from the physical realm, the goal of the evil is not to destroy you in any way, because they can no longer touch your soul since you have been sealed by the Holy Spirit, they can however still interact with you, kinda like the devil on the shoulder thing, only much worse, this is where the tricky part comes it, as a christian, our lives are no longer about us, they are God's and that is to be the primary focus of our existence, when things come along in whatever form and cause us to focus more on them than God, it instantly becomes an idol of sorts, think about peter on the water with Jesus, he was doing fine as long as his gaze and his mind were set upon Jesus, but then he saw all the commotion around him lost his focus, that's when he did his imitation of the titanic, so whatever you do, do not let the unusualness of the things around you allow your focus to be taken from your relationship with God, that is the top priority, and as soon as your gaze falls, the bad guys win, well, just for a while at least
'nuff said for me, later
