Supposedly all angels are actually negative entities in disguise.

Well, they can be, firstly, Angels are not the divine source, only God is, and secondly, there are fallen angels (demons, satan etc) who would love nothing more than to deceive and manipulate you and basically vamperize your source of divine energy so as to sustain themselves. 

If you are not careful, and know not what to ask, you shall fall prey to them, for you ask, and a voice shall answer, but whos? If a spirit comes before you, ask it whom the rightful Lord is, who is the Son of the most High? If the spirit will not confess Jesus, and will not proclaim his glory, then the spirit is not sent by the Father, and is there on its own accord, be wary then. Test your spirits folks, if you wish to contact the angels, let Christ help you, he shall, learn the way to do it, do it earnestly, get that sweet sweet angel loosh. And yes, Angels do watch you constantly, thousands, you don't have one guardian angel, you have many, they know you but you must come to know them first.
