Many people see and hear and feel things that are out of the ordinary.
Guardian Angels certainly have been recorded for centuries. I have a collection of these stories in my head from my readings. GAs rarely appear once, they seem to hang around for life. If they leave for good, they usually say good bye! They appear on the battlefield, during storms, car crashes, all sorts of things, especially events that are happening quickly and with otherwise fatal consequences. In times of extreme peril, the brain is either in flight or fight mode. There is no time for daydreams, hallucinations or any other rational explanation.
The story of the three year old daughter whose father died in "The perfect Storm" of movie and book fame sums up a spirit trapped. She was asleep, woke up and her dead father was in the room, told her he got snagged on a hook, couldnt get out of the boat, he drowned, that was it. Highly unusual for a naieve 3 year old to have such a nightmare. Her mother has no doubt it was real. So her father was one of these trapped spirits, for sure IMO. Children often come across these spirits after someone has died without saying good bye. Wives and Mothers know when their loved one is killed. Sometimes a feeling, sometimes the departed appears in a dream to say goodbye, the person immediately awakes knowing it is all true. Sometimes these spirits appear in broad daylight, a figure standing under a tree, watching, then vanishes.
Now to believe either or both exist, the Bhuddists might be on the right track re a persons spirit, soul, is a separate thing to the body and can exist after death. Now if everything is a result of the brain, i.e. electrical activity, whos to say this electricity cant leave the body and find another home?
Scientists will tell you energy can not be created or destroyed, that the electrical energy of the brain is changed to heat and leaves the body, fair enough.
But if ball lightning can exist, a globe of electricity than can pass through walls and remain intact, act of its own accord, and given that scientists cant really explain ball lightning, then I reckon electricity can leave the brain after death and wander about.
If I can attach electrodes to your scone and read your brain waves, how long until I can read them remotely? Then how long until I can ALTER them remotely? The Russians and Czechs have been working on this for decades and are convinced they can change peoples thoughts. Many old Eastern Bloc countries use psychics to solve crimes all the time and think nothing of it.
There are so many things we dont understand. Not long ago the car wasnt heard of, man flying was considered impossible, the sound barrier would kill you, go to the moon? jeeze your crazy.
As I have said before, it wont belong until we are talking with Dolphins, it will happen in my lifetime. Its all just electricity in the end.
