What is happening to you:
Reality is not a stable rigid place, it part of infinity and as such is subject to change. In an infinite existence that is subject to change anything can happen and it does. You are not what you think you are-you are more than you can possibly imagine because you exist in all these other realities and are connected to your other selves. You can feel them and your "past" self (which in truth is your present self). These "flash backs" are just memories and experiences from your other selves.
why do they happen?
There are an infinite number of reasons, here are a few:
1. Your third eye is activating or over active leading you to "see" beyond the ordinary realm of your reality into other realities using the eyes and bodies of your other selves.
2. A higher/more evolved other self is attempting to contact you or perhaps guide and teach you-unleashing your full potential and leading you move beyond your humanity into what people know as being a super-being or a god(ess).
3. You are experiencing the deja-vu phenomenon. The deja-vu phenomenon is when people feel that they have seen,heard, experienced a certain moment in "time" before even if this seems to defy logic because they have not experienced the events before. These deja-vu events can be anything-such as seeing a face or person you know you have seen before although you've never seen them before in your life.
What is the deja-vu effect?
Our existence is actually an infinity trap-in other words it is a closed existence that follows a specific energy patten which is not really "natural" and is not supposed to exist. This means that the whole of existence is infinite free energy (love energy) except the part of it we are trapped in. If you didn't understand this part don't worry.
The point is our existence/ our universe endlessly implodes and explodes in re-occurring cycles. When the universe comes to an end it implodes and restarts all over again. BUT-there are an infinite number of universes ending and beginning all at once and we feel the effects of this never ending cycle in the form of the deja-vu phenomenon. The reason we experience the feeling of deja-vu is because it really has happened before and is happening again in the infinite now (remember there is no past or future just an endless present)! Lots of times in fact. Everything has happened/is happening so many times that its like an endless echo is forming across time-space an echo of that which has already been and will be again.
You may be experiencing the echo of endlessness, the reason may be that you are evolving beyond being ordinary, your chakras are opening up letting in infinite energy into yourself.
What you should do:
Firstly don't panic or be afraid of your visions, lots of people have them,even me. Calm down and try doing some meditation, do some yoga to re-stabalize and open your chakras more. And remember one thing above all else, belief. Belief is the most powerful thing anyone possesses. it has the ability to change and shift reality/existence. If you get a bad vision of the future DO NOT be afraid of it, it is just a vision of something that may be not something that will be, believing in something that scares you lends it power-power enough to manifest into your reality from another reality. Remember you and no one else is in control of your own "future" and "destiny" as you understand them. If you believe in a positive future it will come to pass. If you really want something in life or existence believe with your heart and soul, believe to the bone and become your belief and you will get what you desire-and don't let anyone dupe you into thinking otherwise.
nonrandom or not random or precisely
The word random has no meaning in this question.
The Random Guess Theorem is a way of thinking in which one allows random acts to take over one's destiny.
Random can be negative, postive, or neutral. It depends if you are using it like "YOu are way to random." then it's a negitave, "You're very random I like that about you." it's positve. Neutral is the same.
The majority of the time the word random is used as an adjective.
Electrons are the particles that move around the nucleus in constant and random motion.
If x = 1 then X is not really a random variable but a constant.
Random Access Memory (RAM)
You might be able to tell if you are a medium by studing with someone who is actually a medium. He or she can help you to discover and refine your talents. As a medium, you might know something will happen before it happens or believe that you can sense spirits and have random visions. These visions might not make sense to you until you are educated as a medium.
gases are in constant random motion
Random Walk: Evolutionary model in which changes in a trait value are conceived as being drawn at random from a constant statistical distribution of evolutionary steps.
Constant random motion of particles
The term "random access" is not normally applied to machines. It is normally used to refer to a form of data storage in which data on any part of the medium can be accessed in constant time.
are in random, constant, straight-line motion
Brownian motion. (It's less commonly called pedesis.)
the concept that tiny particles in constant, random motion make up all matter
According to the Urban Dictionary:Term often used to describe a random, pointless act or outburst. Commonly used in an attempt to draw hilarity where none is found. Family Guy is notorious for many acts of 'monkey cheese' in its various flashbacks to scenes which have little or nothing to do with the plot, but are totally random in an attempt to draw a laugh.
