Is this Proof that a God/Higher Power exists?

            Have you ever thought about in life the strange and different impulses/urges that pop into your head and heart from time to time?  Specifically, have you noticed how you get these impulses/urges to do things - like go get some icecream; or put gas in your car now; help that little old lady out by putting her groceries in the car for her; or go ahead and take that cell phone on the table there that someone left; don't tell the cashier she gave you extra money; or do tell the cashier she gave you extra money  . . .
            Some of these impulses/urges are seemingly neutral, some are overtly negative/evil, while others are very positive/helpful.  So what does this have to do with the existence of a spirit world and/or the existence of a God/Higher Power? 
            Well, I have noticed in my own life that these impulses/"urges" have different intensities to them.  For example, I find that positive impulses/urges that I might experience such as "help that lady over there with her groceries" are generally very gentle messages that seem to be "leading" me into the positive action.  I don't feel forced to act on the positive urge, and in fact I find it fairly easy to reject and to ignore it.  If I do ignore it, I may feel a sadness in my heart and thus want to willingly choose to go back and do what I was being led to do by the positive impulse.  
            On the other hand, my experience with negative impulses/urges is quite different.  When a negative impulse hits such as "let's go shop" when you are on a budget and have no more to spend for the month, this impulse is not a gentle "leading", it is a push to action that feels like there is no other option than to obey the impulse or be constanly bombarded by the impulse to do the action until it is acted on.  To resist a negative impulse requires so much more emotional and mental energy than it does to resist doing a positive impulse.  The "strength" behind the negative impulse feels so much more overwhelming than does the "strength" behind a positive impulse. 

So what is the deal here?  If we are just simple biological creatures, and there is no spiritual world, and it is just us and what we can see and hear and touch, should not positive and negative impulses/urges that we experience have the same strength and require the same amount of energy to resist?
            Could it be that there is a whole other world in which negative forces and positive forces are constantly attempting to influence our decision making process and thus our actions which form our lives in this world?  Could this other world be a world of spiritual beings attempting to guide and/or manipulate us human beings thru impulses/urges someof which are generated by them?  
            In my own life, I have had many experiences beyond simple impulses/urges, when I have awakened in a room at night to feel a "cold presence" next to me . . . with a great overwhelming sense of fear trying to literally swallow up my being.  That presence would immediately leave when I would say "In the name of Jesus Christ" I command you to go.  Other times, I have awakened in the night hour to feel "an overwhelming sense of peace" in the room, which I gladly basked in - this was the Holy Spirit of God.  
            So, something to think about . . . do the differences in the strength and nature of positive impulses/urges versus negative impulses/urges point to the existence of a spiritual world, and thus to God/Higher Power that is not me?  Look forward to your  comments . . .  CJDaniel
