Salt lamps and Ionizers ?

Has any one here experimented with ionsiers or salt lamps to induce states ?

I'm specifically interested in any one like me who can not lucid dream my reasons are health related and quite complex
( http://othersideofeden.tripod.com ) for more details if interested..

But I have noticed that for someone that never dreams at all as these days I have started to get more dreaming experinces and even daymare today while using my salt lamp.

Admittedly its quite large 9 kg which may be a factor but I still find this interesting and am wondering if there there is any way negative ions can be increased to evoke more lucid states so forth.

At this time of writing I purchased ioniser which to try and see how it effects me compared to the salt lamp .

As I said I be very interested to hear others , attempts to induce other states through devices like this or anything else that comes to mind.

thanks
