I have been reading "Psychic Development for Beginners" by William W. Hewitt. I have been diligently doing all of the exercises and things have been starting to happen. One of them is... We just started having an entity(s) in our home. My 9 year old cat, who usually sleeps all day just started running non-stop, playing all day & night for the past 4 days. My 15 month old keeps pointing in the corner of his room saying hi, hi, bye, and follows aroun the room with his finger. He wont sleep at all (he is usually great about his 3 naps a day and all night sleeping), for the past 4 days.
The presence does not feel negative at all.

I want to know how I can maybe contact it/them and/or how to remove it/them. I heard about smudging. Thanks so much

how come sometimes tension is said to be "in both directions", but if you stick a cable horizontally from a wall and hang a mass from the end, the tension is towards the wall? shouldn't there never be any net tension, and if so, why does the value factor in during calculations of other forces??

I know it has something to do with density as for example 600D nylon refers to Denier, also a measure of density.
