1. Get OVR Advanced Toolkit so you can use the playspace mover feature to adjust your avatar's distance from the ground so it lines up with the surface of the bed/sofa/mattress that you plan to sleep on in-game otherwise you will find yourself either floating above the bed or clipping through it, which breaks the immersion.

2. Make sure the world you sleep in is naturally dark or has togglable brightness settings so you can turn it down. Sleeping in a world with bright lights will give you eye strain like sleeping in a room with all the lights turned on.

3. Create a private or friends only instance of the world you decide to sleep in or if you absolutely need to sleep in a public instance because you're hoping to encounter the e-girl of your dreams sleeping next to you when you wake up in the morning then choose a world that doesn't get much player traffic (usually a world with the average player count numbering in the single or double digits or no count listed at all).

Sleeping in a public instance on a world that gets a lot of player traffic is a bad idea because you're likely to run into trolls that are hell-bent on disrupting your VR sleep schedule for shits and giggles.
