Do you like stargazing? Do you wish you could go camping frequently and look up at the sky at night? This may not be feasible if you are working or studying in the city but you can always find alternatives.
For example, you can buy star projector for a nightly show. Turn it on and your room will instantly transform into a planetarium. You can see the virtual stars moving across a makeshift sky as you lie in bed.
You can even set a cloud of nebula in the background for added drama. It will be a sight to behold. You can change the settings for different visual stimuli every time. Some models will even let you set the pulse of the stars in time with music.
Let this be your lullaby as you fall asleep. If you have anxiety, then this should prove to be an excellent distraction.
