Dream like state.

[samf]

well for me, when I have a lucid dream usually the day of the dream I had gone through a point in time where I wasn't actually sure if I was dreaming or not. So I was wondering, is there some sort of mind trick that can trick my mind and myself into not being sure if I'm dreaming, even though I'm not.

That's an interesting thought. I'd recommend meditation. Find a quiet, soothing place where you can be sure you will not be interrupted, get comfortable, but don't lie down. The good old lotus position is always an excellent choice (the type of "indian style" sitting you do on the story-time carpet in Kindergarten, with your feet under your knees, as opposed to over them yogi-style, with your hands resting palm-up on your legs,) but any sitting position in which you can relax without actually nodding off will do. For the goal you have in mind, ie: lucid dreaming later that night, I'd focus on imagining yourself in an environment, interacting with that environment in ways you could only do if you were dreaming. In other words, picture yourself floating, flying, changing colors of your surroundings, performing telekinesis, and the like. But don't just picture an image of you doing this, make it a first-person perspective. Imagine that you feel yourself floating off the ground, don't just picture someone floating who looks like you. Try doing this a few times in a day, prefferably for agood ten or twenty minutes at a time. Longer, if you like, and espescially I'd recommend doing it shortly before you got to sleep. I hope this helps you!
