Yes spirits and ghosts too (earthbound spirits) can definitely affect energy. I've never heard of one using a phone or texting.

The night of my father's death on my 55th birthday after having flown across the USA California to North Carolina, his spirit sat on the bed. And it moved.

He counter-productively said through my thoughts: You better get some sleep, your mother needs your help. I had been nodding off. I was wide awake for two more hours before going to sleep. It was a 6 hour drive to my parents house from the airport.

As a medium/healer I get messages from those you have passed often.
