I believe you mean attuned to Reiki remotely (since this is posted in the Attunement Guidance Bord), if so then;
I have "received" Reiki attunment distantly and since that day (April 2009) I come to feel that distant attunments have nothing to do with Usui system called Reiki but rather something invented by certain western reiki masters influenced by the New Age spirituality.
I was made to believe that I was "attuned to the energy" by the master which from this point of view sounds very much schizophrenic.
Does it work? In my opinion attunments do not work at all nor will they ever in person nor distantly.
No one can attune you to something you have been attuned to since the beginning of days.
Reiki levels are there to show us where we are on our spiritual journey, and they are there to be passed by Masters. In traditional Reiki one is expected to work with Ki energy for longer time before granted the next level.
The same way martial artist advance in training e.g. Karate. Such martial artist do not get to the Black Belt at once. They can get the Black Belt instantly but it means nothing, there is no experience behind it ... it is only a belt nothing more.
Reiki is not an energy but a system a practice which teaches us how to generate Ki energy (Universal Life Force also called Qi, Chi, Prana) in a Spiritual way.
To learn dancing you must find a dancing school. To learn ballet you need to go to a ballet school. Being allowed to practice ballet is the same as being attuned to Reiki 1. After you master it you will receive the diploma from your master.
Attunment or Reiju is the least important part of the Reiki System of Healing. The most important parts are;
1. raising your energy levels daily (raising your frequency) through breathing meditation practice called Hatsurei Ho to unify our Mind and Body in accordance to tune into the Universal Ki flow.
2. daily meditating/contemplating on the 5 Gokai (5 Usui Principles)
3. daily moving Ki through your body by practicing self healing Reiki hand positions.
Masters believing that they hold the power to actually attune you to the Universal Energy are likely delusional and one should be careful not to get side tracked by such.
Attunemnt is more like a welcome note into the practice and the real work is just to begin (breathing meditations, contemplations, self Reiko hand positions).
One can not expect to heal anyone else before raising it's own energy levels first.
Reiki is not the only energy practice through which one can learn to generate Ki (e.g. Kiatsu, Quantum Touch)
They all work with the same energy, the one energy we are all part of since the beginning of time. They are like different dancing schools. It is all dancing but one teaches Tango, other teaches Waltz or ballet, etc ...

So what I was trying to tell you is that no one can attune you to Ki energy but you your self through diligent work. Masters can only welcome you into the Reiki System of Healing by giving Reiju and showing you the steps. If Master is working on it's self (self healing, breathing meditation) than master's energy level will be much higher than the students and the student will feel this through the attunemnt and even through the training. With such Master one will feel inspired and will feel very much glad and positive. You would like to find such Master

Some students tend to "loose" contact with Reiki with irresponsible/unprepared/untrained masters, and even get totally confused with the whole system, some students even get dragged into channeling angels and spirit guides, some even contact dead souls

Such things are not Reiki.
Lots of Love and good Luck on your Journey,
