What is the the ideal direction of the bed in Feng Shui?

For those versed in Feng shui (please, no internet researchers) what is the right Cardinal directions the head of a bed should be oriented to? I've been having sleeping problems, and I had it oriented north-west. Searching the web says south-east it's the ideals direction, but again, nowadays I don't know what sites are ai-generated.

If you can give me a link to a website that may have this information, or have an answer, I'll be forever thankful.

Take care everybody
