==Summoning==
===Crafting===
To craft the  Suspicious Dream, you need:

4 Titanium/Amandtite bars
30 Iron bars
At a Demon/Crimson alter.
===Auto-summon===
To auto summon the Dream Stealer you need to have:
To defeat the Moon Lord

==Fighting==
===Stage 1===
HP:50000 (100000 in expert mode)
Defense: 100 (150 in expert mode)
Damage: 100 (Dream whip) 95 (Contact) 150 (Dream Sword)(Expert mode only)
Once summoned, The Dream Stealer will make it night (if it is day) and throw 3 dream whip attacks. The dream whip  is targeted at the the player as a  1 wide, 6 tall hallow looking whip. If the player gets close, a dream sword starts from the top and goes counter-clockwise. After the boss has 25000 (50500 in expert), stage 2 will start.
===Stage 2===
Health: (as mentioned above) 25000 (50500 in expert mode)
Defense: 75 (100 in expert)
Damage: 150 (Dream whip) (175 in expert) 200 (Nightmare whip)
100 (Dream Sword) 150 (Nightmare cape)
When stage 2 starts, the Dream Stealer does the nightmare whip 5 times, still aimed at the player and same size. And in addition if the Dream Sword fails, a nightmare cape is pulled (Entity data after stage 3) (A nightmare whip then nightmare cape in expert) The boss also has more speed (as fast as a Hermes boots player at full speed). At 10000 HP (25000 in expert), the boss goes into the 3rd stage.
===Stage 3===
HP: 10000 (25000 in expert)
Defense: Same as stage 2 (125 in expert mode)
Damage: Same as 2 but half of it is doubled in expert and much faster, 100 (Wake up attack)
Debuffs: Potion/mana sickness, Woken up (Can't craft until next in-game day)
After stage 2 is over, stage 3 starts. The Dream Stealer does the nightmare attacks (and if you're hit, you get woken up). If you get hit by any other attack, you'll get a random sickness.
===Nightmare cape===
HP: 500
Defense: 50
Attack: 40 (Contact)
Just little annoying minions that were summoned.
