Freddy,
You are trying too hard. don't give yourself a spiritual or mental hernia, by straining. Intuition is a natural process. You can't force nature. (at least not without miracle grow)
Start with something simple that you aren't laying down for. This will help keep you from falling asleep. Try some telepathy. Sit with a deck of cards and quiet your mind and focus. What do you think the top card is? Now check it. make two piles...the ones you got right..the ones you didnt get right. After a few trips thru the deck, you will find your accuracy getting better...even if it is only by one card more...each trip thru.
Don't give up. Getting over your own skepticism is the first half of the battle, and finding confidence to expand on it, will come with the larger pile of "right" cards.
You can also expand this intuition by doing the same card deck thing, but with another person who sees the card and sends you the picture telepathically. This will get better with practice, too.
You can also play with dice. predict what will turn up when you roll the die. It seems like a real small start, but remember that the only job that we start at the top, is digging a hole.
Happy practice.
Blessings,
Rebecca
