Nice hot (or very warm bath) when you won't be interrupted. Quiet is best. Light a few candles around the bathroom and turn off the lights. Watch the lights and shadows entangle on the walls, filling your head with strange, ephemeral images, and your mind will start to "see beyond" the normal. Also, if any particular candle flame starts getting playful then give it some attention too. I mean, as long as it's not lighting something on fire.
If you don't have a bathroom with a tub then you can just (carefully) place a few candles around your room. Get in some loose clothes and watch from bed, but you
have to be sitting up so you don't fall asleep. Then yeah, just pick some form that stands out more and go with it...
BTW, best way to extinguish candles, especially in jars or votives, is to close the tops tightly with aluminum foil. The flames will starve for air and any leftover smoke will stay in the jar. Wait 'til they cool before unwrapping them and you won't have a room full of smoke.Best wishes.
