Interacting with the 4th dimensional planes is not the same as your usual 3D interactions.
4th dimensional experiences are based on the INTENSITY of connection. To perceive energy in the 4th dimension there needs to be an energetic connection made.
The more intense this energetic connection, the more intense an 'experience' you have.
Time operates very differently as well. It operates from a mode of perception, and perception is based on intensive connection. During an interaction in the 4th dimensional realm there will be a natural fading in to and out of the experience. It is not a matter of 'you're here, then gone'. No. You start connecting with another energy, reach peak intensity of the experience, then you start disconnecting. It is not time based, the experience is based on the intensity of energy of the connection.
Just remember the fading in and out process.
