Experiences produced by particular strain can vary wildly even for the same user, so it boils down to experimenting with different strains in different settings and finding out what works for you. Some users report that mixing strains of "haze" family tends to produce strong closed-eye visuals and mild open-eye ones.
If your vision is affected by visual snow (https://en.wikipedia.org/wiki/Visual_snow) or you are prone to have noticeable phosphene images with closed eyes, then it may be sufficient to simply focus on them while being high. The drug will greatly amplify your natural "hallucinations", subjectively up to the level of mild dose of psylocibin or LSD. Of course, taking those classic psychedelics is a more reliable way to produce visuals, but they come with headspace which is quite different (and for some less desirable and comfortable) from weed-induced one.
The same focusing technique can work for monotonic sounds - it's quite amusing to observe how fridge's buzz turns into full-blown symphony :).
