I don't think DeJa Vu is paranormal. I think our brains make millions upon millions of small connections every day. Think of how many little details your brain picks up on, but just stores them "just in case" you ever need them. I think, when you're experiencing DeJa Vu, it's just your brain being triggered by a small detail (a sight, sound, taste, small) and that instantaneous trigger pulls any number of details from your brain to try and create a memory or a foundation that makes it make sense. I have DeJa Vu frequently and I've noticed that my moments of DeJa Vu are almost always connected to a strong emotion. I also think that we dream and all those dreams file themselves away in our subconscious. It wouldn't surprise me if DeJa Vu was just your brain locking in on a dream memory regarding similar circumstances. But, wtf do I know?
