Sudden Fall In Dreams / 梦中忽然下坠感


Have you ever try this? You're sleeping, either deep sleep, dreaming or not, suddenly you felt yourself falling, any kind of fall, the next thing you know that fall jolts you awake and you're sitting on your bed. Here are a few ideas:

Falling from the Skies: Flying downwards from the heavens may symbolize a "fall from grace." Has an authority figure expressed disappointment in you? Have you embarrassed yourself by recent behaviors?

Being Pushed: Loss of empowerment. Getting fired or looked over in a promotion you were hoping for. Or, being bullied or forced into an uncomfortable situation.

Stumbling as you Walk: Feeling as if you have lost your way in your life path. Overly anxious about finding your life purpose.

Jumping without a Parachute: Being or feeling unsupported by others.



Being Jerked Awake: Have you ever been awoken from a falling dream? Or felt a jerking sensation in your body that jolts you awake? One theory for this happening is that your spiritual body has returned from its astral flight and that "jolt" is the dreamer experiencing re-entry into the physical realm.


===================================================================

你有试过在睡着的时候,忽然有从高处下坠的感觉,惊醒过来?我在网上搜索了几个解释:

人体在睡眠时,感觉机能减退,如嗅觉、听觉、视觉及触觉等感觉器官功能下降;运动机能也降低,如肌肉的反射运动和紧张度减弱,骨胳肌非常松驰;机体的代谢率降低,血压可下降10%、心跳和呼吸可减少20%、体温下降、尿量减少、瞳孔缩小等。总之,机体的一切生理机能在睡眠时均减慢,处于恢复、休息状态。青少年正值发育时期,应注意保持充足的睡眠,一般每天有九小时睡眠时间为宜。

睡眠作为一个生理过程,由浅入深,深浅交替,一种在脑电图上表现为慢波,这一睡眠阶段叫“慢波睡眠”;另一种在脑电图上表现为快波,叫“快波睡眠”。快波睡眠是深睡状态,这时眼球快速运动,肌肉松驰,难以唤醒。在整个睡眠中“快波睡眠”与“慢波睡眠”交替出现。

人体在睡眠过程中,受体内外刺激的干扰,引起大脑皮层的个别细胞群处于兴奋状态,从而产生了梦。如由于白天行走劳累,在刚入睡时,就会梦见走路或一只脚踏入坑里,并通过运动中枢引起蹬腿动作,这时睡眠较浅,常因蹬腿而醒来;再如当睡眠时听以滴水声响时,会梦见下雨。在入睡时做的梦往往不会记住,而在觉醒前做的梦,在觉醒后则易回忆。一般梦多是在快波睡眠时出现,是一种正常生理现象。

睡眠时,注意减少对身体的各种刺激,如不要受凉、睡前不要看惊险小说、是晚饭不要过饱等,这样有利于睡眠。有人认为梦是祸、福的预兆,这是毫无科学根据的。


另一个说法是说这现象属于脑疲劳,建议正常作息一段时间,同时营养跟上,会有显著的效果。

脑疲劳症状
1.早晨醒来懒得起床。
2.走路抬不起腿。
3.不想参加社交,不愿见陌生人。
4.懒得讲话,说话声音细而短,自觉有气无力。
5.坐下后不愿起来,时常呆想发愣。
6.说话、写作业时常出错。
7.记忆力下降,反应迟钝。
8.提不起精神来,过分地想用茶或者咖啡提神。
9.口苦、无味、食欲差,感到饭菜没有滋味,厌油腻,总想在饭菜中加些刺激性调料。
10.心理紧张,精神不振,心绪不宁,思维紊乱,情绪波动,注意力分散,头晕头痛等。
11.耳鸣、头昏、目眩、眼前冒金星、烦躁、易怒。
12.眼睛疲劳,哈欠不断。
13.下肢沉重,休息时总想把脚架在桌上。
14.入睡困难,想这想那,易醒多梦。
15.打盹不止,四肢像抽筋一般。

如果有上述2至4项情况时,说明轻微疲劳,需要立即休息;有5项以上是重度疲劳,也许潜伏着疾病,这时你应当马上去医院检查。

如果出现了轻微的脑疲劳现象,也不必过分紧张。应放松身心,学会科学用脑,做到劳逸适度,并注意饮食与睡眠,也可以做一些适量的脑部运动。
