Enveloped by the Void

As you reach your hand into the void, black nothingness begins to creep over your body, until your entire form is covered by dark infinite oblivion. For the duration of the spell, you are suspended in a pocket dimension that you can not be pulled out of. While there you can see around you in monotone and can not take damage, however, your movement speed is zero, and no sounds or matter can pass in or out of the void. The only way to leave the pocket dimension is to drop the spell or to wait for it to expire.
