篇四：独自睡觉作文

独自睡觉作文

独自睡觉的夜晚

在我八岁时，我的表妹小宇总说她都是自己一个人独自睡觉，还笑话我说比她大还和妈妈一起睡觉。

我很不服气，对她说：“我今天晚上就自己睡，别以为就只有你会自己睡！”我很生气地跑了，而她在后面“咯咯”地笑。

晚上，我求妈妈让我自己睡，但妈妈说：“天气凉，等天气热了再自己睡吧！”我又求了好几次，妈妈才答应了我。

一开始，房间外的灯亮着，我不感到害怕，一个人独自睡觉真好，大大的床只有我一个人，一会儿就睡着了。到了深夜，不知怎么的，我迷迷糊糊地就醒了，房间外面的灯是灭的，伸手不见五指，我突然心里感到前所未有的惊慌。听到了一点响动，我感到了害怕，我的心跳也加速起来。仔细一听，原来是一阵风吹过，我哭笑不得，但是我还是跑到妈妈的床上睡觉去了。

第二天，我决定再独自睡一次。那天，太阳留恋地迟迟舍不得离去，我一直盼呀盼地很着急。后来，夜神急了，从口袋里拿出了黑色的幕布向天空扔去，月亮和星星才笑眯眯地爬上了夜空。我一个人独自静静地睡了。半夜里，我又醒了，风儿还是在轻轻地吹，当我看见窗外挂满了星星的夜空，我不再害怕了。那一夜我安静地睡到了天亮。

那天，是我感到很美妙的一个长夜，因为我>长大了。如今想起那一夜，我还是感到很美妙，因为天空中有那么多的星星在陪伴着我。
