It's an hallucinogenic plant, I wouldn't say it helps you remember dreams, it makes you hallucinate.
I wouldn't recommend taking it, there is little known about all it's functions on the body.
I do not think it will make you dependent though.
Amanita Muscaria in small doses is better from dreaming, some really awesome and memorable dreams come from it.
I suggest mastering good sleep first, go to bed early, eat well, keep a dream journal next to your bed.
If you have a dream write it down straight away!
You will not remember them all the time though.
I find I dream more vividly and remember them when I am exposed to new things.
