This conspiracy theory of scientists keeping it from us is a belief. It may be true, it may be not, or both, or neither.
But I am almost certain that scientists don't know anything about telepathy, because it is not a material phenomena.
And neither is awareness. That is why it eludes science. Awareness and telepathy are not material or substantial.
Do you want awareness and telepathy to be a material brain phenomena? Do you believe that it is a brain phenomenon?
Then why do we think that scientists are an authority on awareness? What information would they have that you don't have
that you would need? A lucid dreamer thinking that scientists are withholding secrets of awareness and the mind?
The laboratory for investigating the mind is the mind itself, and lucid dreamers are the ones in that laboratory.

Telepathy is more of a heart phenomena, but not the physical organ of the heart.
And awareness! Find out what awareness is and you know the nature of the whole universe.
