The thoughts of every person are not a physical or tangible thing. Everyones thoughts radiate outward in what could possibly be considered a “thought field.” Our thought fields can interact with each others’ and influence thoughts in other people. This phenomenon is known as collective conciousness and is supported by numerous well constructed experiments by universities. Time is linear with parallel universes created by our various decisions, but thought (because it does not physically exist) transcends time and space, radiating in every direction of the 4 dimensions (space/time).
Events that have already happened or will potentially happen can bleed into the present through thought and subconscious. Events that are happening in an alternate present can bleed into the actual present in the same way. The more significant the event the more likely it is to make an impact.
Thought fields travel not only forwards and sideways through time but also backwards. There are no such things as ghosts; however, if a dead person has a strong connection with a place people may think or feel that the person is still there.
If our thought fields also extend backwards, they may also be able to interact with past thought fields. This is may be proof that the deceased are still with us “in spirit.” "Love at first sight" is also explained by this theory, because by seeing someone that you will someday love, you create a connection between your current thought field and your future thought field.
