"I simply cannot retrieve information from my unconscious mind."
This is actually impossible.

"but I feel "blocked" by the conscious mind"
This of course is VERY common.
'Feel' clear, open, easy and all-knowing instead.

"I just cannot unlock its potentials"
Yes you can.

Here is some help:

Repeat 100 times out-loud with emotional intensity.
======================
I AM I
I Feel as I please
I am eternal
I dare 'to know'
I CAN and I AM
So It Is!
======================
