I believe in oneness so my question is, if this is true can you “talk” with the other person just by being alone with them and connecting to their energies?

Oneness means that nothing is separate from the energy of creation, that everything that happens affects all. So, the reality is that we are all connected but we just do not accept it.  Most people reject this as the ego rules and life is about them. Answer:

However, it is possible for two or more people to connect if they are in the right emotional, mental and spiritual space and this can be engendered when two people of spiritual like mind choose to connect spiritually through the aura and chakras. Here they can talk energetically move energy back and forth to each other.

No doubt many people have connected through sexual energy to another, but it is also possible to connect spiritually through the aura and chakras during sexual practices such as Tantra.
