Stefanie Schuster asked: Why do we dream? In 2013 The Guardian published an article called “The 20 big questions in science”. Most of them are still considered to be the biggest questions in science, one of them being “Why do we dream?”. With this new interac- tive format, we asked this question on our blog and collected answers over the last three months. And we got great replies and thoughts! tes solida - n o c in el P.: o may the bra Micha ep is when we dream s days le n he ‘REM s s and whe replaying t ie h r it o w m me r do regula as to hout eam- be it h it w dr .’ nes events ance decli pendent of e m d r ‘Perfo ut maybe in (b p e le s ing?).’ Jens K ‘I cou linzing : ld im phen a ome gine tha non centl t dre o y a ries.’ encoded f the rea ms are a c a u tobio tivation n epi- ‘Duri grap ng R hical of re- E tual mem realit M sleep o- ie t erati ve m s in orde he brain r to o sens odel creat o e p ‘We c ry input.’ it uses t timize th s vir- o pr e an d edict gen- r in th e rea eam with futur l wor o e ut ac ld.’ ting all of it ou t in ave a time David Sk: rtant to h d o n p a , im s e te b a nsolid o c ‘It could , ts c e fl uch brain re s with a m n o which the ti a lid a v om tional rruption fr does emo ithout inte w lled y o it c tr a n p o a c being t higher c u o h it w brain e and high order the outsid d n a l a ic g trate by more s ’ . regions Steffi: ‘Dreams help to m aintain a fight-or-fl nd train ight resp th onse as is most a the amyg e ctive duri dala ng dream ing.’ GizAltan: ‘Freud suggested that dreams are (for) “… disguised fulfillments of repressed wish- es.”’ ‘In the end, dreams are end-products (or side products) of some neurobiological processes.’ Johanna Salu : ‘For me pe rsonally, the purpose of dreams is to entertain and provide food for thought.’ ‘Another inte resting cont radiction in dreaming is evidenced by the fact that one frequent ly feels like pa ssive partici- pant in a stor y, a characte r that things are happenin g to, yet the en tire concoction of one’s own min story is a d.’ ‘Dreaming po ses lots of intellectually stimulating qu estions while simultane- ously giving m e the ability to fly.
