It is often said that when we die it's only the beginning of everlasting life! I feel life as we know it is some how connected to the other side! It's like 2 alternate worlds coexisting with one another! Only one runs a time frame a lil quicker than ours. For me that explains dejavue, we enter one alternate universe and it takes a while for this reality to catch up so we get that feelling like we've been through this before! To me when we die we experience shades of gray and lite fog all around with everything a lil dim. I think the movie Silent Hill explains that very well! Some people die and they don't realize it so they walk around in this alternate universe exactly like ours but with out the colors of life. And some people claim to see the dead, but thats only because from time to time they cross over to this universe lost for a min and there is always someone who will see them! Even for a brief minute! I just had to share that analogy with my peeps and readers to give you all a lil something to think about! So if your in your house and swear you just saw a shadow pass by and then you look and theres nothing there, you never know chances are there probably was! Maybe some poor shade of grey crossed over here and is looking for his way back! Think about it!
