YOU DON"T NEED DRUGS!!
Be still and listen. Quiet your mind to complete silence and become the pure consciousness of the observer. I would suggest you find a place that is quiet or where you can be alone and make it a habit to spend time in quiet meditation on clearing your mind of all activity so that you can begin to feel your connection to everything else.
If you want to see U.F.O, Some will laugh but I think it is this easy.
1) Picture yourself wherever you are and think something like "I would sure like to see a UFO or an etv one day so I will know what others are talking about"
2) see the thought in your minds eye as going out into the heavens, space etc...
3) think the thought when you look at the sky and take time to look at the sky or take planned camping trips or whatever to get you to less populated places. you are bound to see something sooner or later for there is much activity.
BEST PLACE to spot this type of activity is on a hill or mountain that overlooks a highly populated area or city
P.S don't forget your camera this field of study desperately needs more documentation and study.
I wish you the best of luck and success on your personal path to spiritual and physical evolution
